为什么 hbase 无法运行在 docker 中?
我需要让 hbase 跑在 arm 上
而且想用 docker
所以我写了下面的 Dockerfile
FROM python:3.10-buster RUN . /etc/os-release && cat > /etc/apt/sources.list <<EOF

RUN tar xvf /root/hbase-2.4.17-src.tar.gz
我先跑在 x86 上,看看 ok 不 ok ,所以上面的 java home 是 amd64 的
但是不行

在我的虚拟机上,直接 JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 bash bin/hbase-daemon.sh start master 就行了!
我的虚拟机是 ubuntu18.04,可以直接 sudo apt install openjdk-8-jdk
,所以有 jdk8,但是用的 debian10 已经没有 debian8 了,我就用 jdk11 了
https://hbase.apache.org/book.html#java
不知道是不是因为 jdk11 引起的
应该不是 jdk 的问题,因为我换成 ubuntu20 的镜像之后,安装 jdk8 之后也是不行

RUN echo "export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-arm64" | tee -a /etc/profile >/dev/null
注意,这是 arm 版本
docker run --rm -it ponponon/hbase-arm-focal bash

不是用 harisekhon/hbase 是因为在 apple arm mac 上会报错 TTransportException: TTransportException(type=4, message='TSocket read 0 bytes')

使用下面的 python 脚本连接
import happybase# 定义HBase连接信息
host = '192.168.38.191' # HBase主机名或IP地址
host = '127.0.0.1' # HBase主机名或IP地址
port = 9090 # HBase端口,默认为9090
# 建立HBase连接
connection = happybase.Connection(host=host, port=port)
# 获取所有表名
table_names = connection.tables()
# 删除所有表
print('删除所有表')
for table_name in table_names:
connection.delete_table(table_name, disable=True)
table_name = 'my_table' # 表名
column_families = {
'cf1': dict(), # 第一个列族
'cf2': dict() # 第二个列族
}
# 建立HBase连接
connection = happybase.Connection(host=host, port=port)
# 创建表
print('创建表')
connection.create_table(table_name, column_families)
# 获取表对象
table = connection.table(table_name)
# 插入数据
print('插入数据')
row_key = 'row1'
data = {
'cf1:column1': 'value1',
'cf1:column2': 'value2',

}
table.put(row_key, data)
# 获取数据
row = table.row(row_key)
print(row)
# 扫描数据
print('读取数据')
scan_result = table.scan(row_start=row_key, row_stop=row_key)
for key, value in scan_result:
print(key, value)
# 删除数据
table.delete(row_key)
# 关闭连接
connection.close()
会报错

回答:
解决了,可看: 借助 Docker 在 Arm 设备上运行 Hbase
回答:
你直接使用hbase的基础镜像不就行了
docker run -d -h 127.0.0.1 -p 2181:2181 -p 8080:8080 -p 8085:8085 -p 9090:9090 -p 9000:9000 -p 9095:9095 -p 16000:16000 -p 16010:16010 -p 16201:16201 -p 16301:16301 -p 16020:16020 --name hbase harisekhon/hbase
如果想自己改造就
Dockerfile
FROM harisekhon/hbasexxxxxxx
.......
