一、下载安装IDEA

IDEA2020.2.3版本：https://www.cnblogs.com/liugp/p/13868346.html

最新版本安装详情请参考：https://www.jb51.net/article/196349.htm

二、搭建本地hadoop环境（window10）

可以看我之前的文章：大数据Hadoop之——部署hadoop+hive环境（window10环境）

当然也可以部署在linux系统上，远程连接，可以参考以下两篇文章：

大数据Hadoop原理介绍+安装+实战操作（HDFS+YARN+MapReduce）

大数据Hadoop之——数据仓库Hive

三、安装Maven

可以看我之前的文章：Java-Maven详解

四、新建项目和模块

1）新建maven项目

因为之前我创建过了，所以会标红

把自动生成的src删掉，以后是通过模块来管理项目，因为一个项目一般会包含很多模块。

2）新建flink模块

目录结构，新建没有的目录

设置目录属性

因为之前创建过项目，所以这里创建一个新项目来演示：bigdata-test2023

五、配置IDEA环境（scala）

1）下载安装scala插件

File-》Settings

intellij IDEA本来是不能开发Scala程序的,但是通过配置是可以的，我之前已经装过了，没装过的小伙伴，点击这里安装即可。

2）配置scala插件到模块或者全局环境

添加完scala插件之后就可以创建scala项目了

3）创建scala项目

创建Object类

【温馨提示】类只会被编译，不能直接被执行。

4）DataStream API配置

1、Maven配置

在flink模块目录下pom.xml配置如下内容：

【温馨提示】这里的scala版本要与上面插件版本一致

<dependency>
	<groupId>org.apache.flink</groupId>
	<artifactId>flink-scala_2.12</artifactId>
	<version>1.14.3</version>
	<scope>provided</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.flink/flink-streaming-scala -->
<dependency>
	<groupId>org.apache.flink</groupId>
	<artifactId>flink-streaming-scala_2.12</artifactId>
	<version>1.14.3</version>
	<scope>provided</scope>
</dependency>
<dependency>
	<groupId>org.apache.flink</groupId>
	<artifactId>flink-streaming-scala_2.12</artifactId>
	<version>1.14.3</version>
	<scope>provided</scope>
</dependency>

【问题】IDEA 在使用Maven项目时，未加载 provided 范围的依赖包，导致启动时报错

【原因】就是 Run Application时，IDEA未加载 provided 范围的依赖包，导致启动时报错，这是IDEA的bug

【解决】在IDEA中设置

2、示例演示

（官网示例）

package com
import org.apache.flink.streaming.api.scala._
import org.apache.flink.streaming.api.windowing.assigners.TumblingProcessingTimeWindows
import org.apache.flink.streaming.api.windowing.time.Time
object WindowWordCount {
  def main(args: Array[String]) {
    val env = StreamExecutionEnvironment.getExecutionEnvironment
    val text = env.socketTextStream("localhost", 9999)
    val counts = text.flatMap { _.toLowerCase.split("\W+") filter { _.nonEmpty } }
      .map { (_, 1) }
      .keyBy(_._1)
      .window(TumblingProcessingTimeWindows.of(Time.seconds(5)))
      .sum(1)
    counts.print()
    env.execute("Window Stream WordCount")
  }
}

在命令行起一个9999端口的服务

$ nc -lk 9999

运行测试

5）Table API & SQL配置

1、Maven配置

<dependency>
	<groupId>org.apache.flink</groupId>
	<artifactId>flink-table-planner_2.12</artifactId>
	<version>1.14.3</version>
	<scope>provided</scope>
</dependency>
<dependency>
	<groupId>org.apache.flink</groupId>
	<artifactId>flink-streaming-scala_2.12</artifactId>
	<version>1.14.3</version>
	<scope>provided</scope>
</dependency>
<dependency>
	<groupId>org.apache.flink</groupId>
	<artifactId>flink-table-common</artifactId>
	<version>1.14.3</version>
	<scope>provided</scope>
</dependency>

2、示例演示

这里使用filesystem，不需要引用相应得maven配置，像kafka，ES等连接器是需要引入相应的maven配置，但是这里使用到了format csv，所以得引入相应得配置，配置如下：

更多连接器的介绍，你看官方文档

<!-- format csv 下面会用到-->
<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-csv</artifactId>
    <version>1.14.3</version>
</dependency>

源码

package com
import org.apache.flink.table.api._
object TableSQL {
  def main(args: Array[String]): Unit = {
    val settings = EnvironmentSettings.inStreamingMode()
    val tableEnv = TableEnvironment.create(settings)
    // create an output Table
    val schema = Schema.newBuilder()
      .column("a", DataTypes.STRING())
      .column("b", DataTypes.STRING())
      .column("c", DataTypes.STRING())
      .build()
    tableEnv.createTemporaryTable("CsvSourceTable", TableDescriptor.forConnector("filesystem")
      .schema(schema)
      .option("path", "flink/data/source")
      .format(FormatDescriptor.forFormat("csv")
        .option("field-delimiter", "|")
        .build())
      .build())
    tableEnv.createTemporaryTable("CsvSinkTable", TableDescriptor.forConnector("filesystem")
      .schema(schema)
      .option("path", "flink/data/")
      .format(FormatDescriptor.forFormat("csv")
        .option("field-delimiter", "|")
        .build())
      .build())
    // 创建一个查询语句
    val sourceTable = tableEnv.sqlQuery("SELECT * FROM CsvSourceTable limit 2")
    // 将查询到的数据转到下游存储
    sourceTable.executeInsert("CsvSinkTable")
  }
}

6）HiveCatalog

1、Maven配置

• 基础配置

<!-- Flink Dependency -->
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-connector-hive_2.11</artifactId>
  <version>1.14.3</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-table-api-java-bridge_2.11</artifactId>
  <version>1.14.3</version>
  <scope>provided</scope>
</dependency>
<!-- Hive Dependency -->
<dependency>
    <groupId>org.apache.hive</groupId>
    <artifactId>hive-exec</artifactId>
    <version>3.1.2</version>
    <scope>provided</scope>
</dependency>

【温馨提示】在IDEA中scope设置provided的时候，必须对应的运行文件设置加载provided的依赖到classpath

• Log4j2 配置（log4j2.xml）

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
        </Console>
        <RollingFile name="RollingFile" filename="log/test.log"
                     filepattern="${logPath}/%d{YYYYMMddHHmmss}-fargo.log">
            <PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
            <Policies>
                <SizeBasedTriggeringPolicy size="10 MB" />
            </Policies>
            <DefaultRolloverStrategy max="20" />
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="info">
            <AppenderRef ref="Console" />
            <AppenderRef ref="RollingFile" />
        </Root>
    </Loggers>
</Configuration>

• 配置hive-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <!-- 所连接的 MySQL 数据库的地址，hive_remote2是数据库，程序会自动创建，自定义就行 -->
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true&amp;useSSL=false&amp;serverTimezone=Asia/Shanghai</value>
    </property>
    <!-- MySQL 驱动 -->
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
        <description>MySQL JDBC driver class</description>
    </property>
    <!-- mysql连接用户 -->
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>root</value>
        <description>user name for connecting to mysql server</description>
    </property>
    <!-- mysql连接密码 -->
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>123456</value>
        <description>password for connecting to mysql server</description>
    </property>
    <property>
        <name>hive.metastore.uris</name>
        <value>thrift://localhost:9083</value>
        <description>IP address (or fully-qualified domain name) and port of the metastore host</description>
    </property>
    <!-- host -->
    <property>
        <name>hive.server2.thrift.bind.host</name>
        <value>localhost</value>
        <description>Bind host on which to run the HiveServer2 Thrift service.</description>
    </property>
    <!-- hs2端口 默认是1000，为了区别，我这里不使用默认端口-->
    <property>
        <name>hive.server2.thrift.port</name>
        <value>10001</value>
    </property>
    <property>
        <name>hive.metastore.schema.verification</name>
        <value>true</value>
    </property>
</configuration>

【温馨提示】必须启动metastore和hiveserver2服务，不清楚的小伙拍可以参考我之前的文章：大数据Hadoop之——部署hadoop+hive环境（window10环境）

$ hive --service metastore
$ hive --service hiveserver2

2、Hadoop与Hive Guava冲突问题

【问题】Hadoop和hive-exec-3.1.2的Guava的版本冲突导致Flink任务启动异常

【解决】删掉%HIVE_HOME%lib目录下的guava-19.0.jar，再把%HADOOP_HOME%sharehadoopcommonlibguava-27.0-jre.jar复制到%HIVE_HOME%lib目录下。

3、示例演示

package com
import org.apache.flink.table.api.{EnvironmentSettings, TableEnvironment}
import org.apache.flink.table.catalog.hive.HiveCatalog
object HiveCatalogTest {
  def main(args: Array[String]): Unit = {
    val settings = EnvironmentSettings.inStreamingMode()
    val tableEnv = TableEnvironment.create(settings)
    val name            = "myhive"
    val defaultDatabase = "default"
    val hiveConfDir     = "flink/data/"
    val hive = new HiveCatalog(name, defaultDatabase, hiveConfDir)
    // 注册catalog，会话结束自动消失
    tableEnv.registerCatalog("myhive", hive)
    // 显示有多少个catalog
    tableEnv.executeSql("show catalogs").print()
    // 切换到myhive 的catalog
    tableEnv.useCatalog("myhive")
    // 创建库，已经持久化到hive了，会话结束依然存在
    tableEnv.executeSql("CREATE DATABASE IF NOT EXISTS mydatabase")
    // 显示有多少个database
    tableEnv.executeSql("show databases").print()
    // 切换数据库
    tableEnv.useDatabase("mydatabase")
    // 切换表
    tableEnv.executeSql("CREATE TABLE IF NOT EXISTS user_behavior (
  user_id BIGINT,
  item_id BIGINT,
  category_id BIGINT,
  behavior STRING,
  ts TIMESTAMP(3)
) WITH (
 "connector" = "kafka",
 "topic" = "user_behavior",
 "properties.bootstrap.servers" = "hadoop-node1:9092",
 "properties.group.id" = "testGroup",
 "format" = "json",
 "json.fail-on-missing-field" = "false",
 "json.ignore-parse-errors" = "true"
)")
    tableEnv.executeSql("show tables").print()
  }
}

看下面通过hive客户端连接查看上面程序创建的库和表，依然是存在的

从上面验证显示，一切ok，记得开发的时候引入连接器的时候需要引入对应的maven配置

7）下载flink并本地启动集群（window）

下载地址：https://flink.apache.org/downloads.html

flink-1.14.3：https://dlcdn.apache.org/flink/flink-1.14.3/flink-1.14.3-bin-scala_2.12.tgz

【温馨提示】在新版中start-cluster.cmd和flink.cmd已经找不到了，但是可以从以前的版本中复制过来。下载下面的老版本

flink-1.9.1：https://archive.apache.org/dist/flink/flink-1.9.1/flink-1.9.1-bin-scala_2.11.tgz

其实主要从flink-1.9.1中copy以下两个文件到新版本中

下载比较慢，所以我这里还是提供一下这两个文件

• flink.cmd

endlocal

启动flink集群很简单，只要双击start-cluster.bat

通过sql客户端验证一下

$ SELECT "Hello World";

【错误】NoResourceAvailableException: Could not acquire the minimum required resources

【解决】是因为资源太小，不足以跑任务，扩大配置，修改如下配置：

jobmanager.memory.process.size: 3200m
taskmanager.memory.process.size: 2728m
taskmanager.memory.flink.size: 2280m

但是我这里调大了还是太小了，自己电脑配置有限，如果有小伙伴的配置高，可以再调大验证一下。

8）完成版配置

            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-mapreduce-client-common</artifactId>
            <version>3.3.1</version>
            <scope>provided</scope>
        </dependency>
        <dependency>

            <scope>provided</scope>
        </dependency>
        <!--hadoop end-->
    </dependencies>
</project>

2、log4j2.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
        </Console>
        <RollingFile name="RollingFile" filename="log/test.log"
                     filepattern="${logPath}/%d{YYYYMMddHHmmss}-fargo.log">
            <PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
            <Policies>
                <SizeBasedTriggeringPolicy size="10 MB" />
            </Policies>
            <DefaultRolloverStrategy max="20" />
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="info">
            <AppenderRef ref="Console" />
            <AppenderRef ref="RollingFile" />
        </Root>
    </Loggers>
</Configuration>

3、hive-site.xml配置

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <!-- 所连接的 MySQL 数据库的地址，hive_remote2是数据库，程序会自动创建，自定义就行 -->
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true&amp;useSSL=false&amp;serverTimezone=Asia/Shanghai</value>
    </property>
    <!-- MySQL 驱动 -->
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
        <description>MySQL JDBC driver class</description>
    </property>
    <!-- mysql连接用户 -->
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>root</value>
        <description>user name for connecting to mysql server</description>
    </property>
    <!-- mysql连接密码 -->
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>123456</value>
        <description>password for connecting to mysql server</description>
    </property>
    <property>
        <name>hive.metastore.uris</name>
        <value>thrift://localhost:9083</value>
        <description>IP address (or fully-qualified domain name) and port of the metastore host</description>
    </property>
    <!-- host -->
    <property>
        <name>hive.server2.thrift.bind.host</name>
        <value>localhost</value>
        <description>Bind host on which to run the HiveServer2 Thrift service.</description>
    </property>
    <!-- hs2端口 默认是1000，为了区别，我这里不使用默认端口-->
    <property>
        <name>hive.server2.thrift.port</name>
        <value>10001</value>
    </property>
    <property>
        <name>hive.metastore.schema.verification</name>
        <value>true</value>
    </property>
</configuration>

六、配置IDEA环境（java）

1）maven配置

<?xml version="1.0" encoding="UTF-8"?>

【温馨提示】其实log4j2.xml和hive-site.xml不区分java和scala的，为了方便这里还是再复制一份。

2）log4j2.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
        </Console>
        <RollingFile name="RollingFile" filename="log/test.log"
                     filepattern="${logPath}/%d{YYYYMMddHHmmss}-fargo.log">
            <PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
            <Policies>
                <SizeBasedTriggeringPolicy size="10 MB" />
            </Policies>
            <DefaultRolloverStrategy max="20" />
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="info">
            <AppenderRef ref="Console" />
            <AppenderRef ref="RollingFile" />
        </Root>
    </Loggers>
</Configuration>

3）hive-site.xml配置

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <!-- 所连接的 MySQL 数据库的地址，hive_remote2是数据库，程序会自动创建，自定义就行 -->
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true&amp;useSSL=false&amp;serverTimezone=Asia/Shanghai</value>
    </property>
    <!-- MySQL 驱动 -->
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
        <description>MySQL JDBC driver class</description>
    </property>
    <!-- mysql连接用户 -->
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>root</value>
        <description>user name for connecting to mysql server</description>
    </property>
    <!-- mysql连接密码 -->
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>123456</value>
        <description>password for connecting to mysql server</description>
    </property>
    <property>
        <name>hive.metastore.uris</name>
        <value>thrift://localhost:9083</value>
        <description>IP address (or fully-qualified domain name) and port of the metastore host</description>
    </property>
    <!-- host -->
    <property>
        <name>hive.server2.thrift.bind.host</name>
        <value>localhost</value>
        <description>Bind host on which to run the HiveServer2 Thrift service.</description>
    </property>
    <!-- hs2端口 默认是1000，为了区别，我这里不使用默认端口-->
    <property>
        <name>hive.server2.thrift.port</name>
        <value>10001</value>
    </property>
    <property>
        <name>hive.metastore.schema.verification</name>
        <value>true</value>
    </property>
</configuration>
