唉，网上的资料比较少，找了好久，压根不知道如入告诉 phoenix 客户端来使用 kerberos 啊。。

然后就想到了，这东西开源的应该有相关的单元测试吧。。啊哈哈哈哈哈哈，果然

https://github.com/apache/phoenix/blob/master/phoenix-core/src/test/java/org/apache/phoenix/jdbc/SecureUserConnectionsTest.java

private String joinUserAuthentication(String origUrl, String principal, File keytab) {
        StringBuilder sb = new StringBuilder(64);
        // Knock off the trailing terminator if one exists
        if (origUrl.charAt(origUrl.length() - 1) == PhoenixRuntime.JDBC_PROTOCOL_TERMINATOR) {
            sb.append(origUrl, 0, origUrl.length() - 1);
        } else {
            sb.append(origUrl);
        }
        sb.append(PhoenixRuntime.JDBC_PROTOCOL_SEPARATOR).append(principal);
        sb.append(PhoenixRuntime.JDBC_PROTOCOL_SEPARATOR).append(keytab.getPath());
        return sb.append(PhoenixRuntime.JDBC_PROTOCOL_TERMINATOR).toString();
    }

通过 url 拼接就行了！！ 测试代码：

public class Main {
    public static void main(String[] args) throws ClassNotFoundException, LoginException {
        System.setProperty("java.security.krb5.conf", "/app/conf/krb5.conf");
        Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
        try (Connection connection = DriverManager.getConnection("jdbc:phoenix:node1,node2,node3:storm-miras:/app/conf/storm.headless.keytab");
             PreparedStatement preparedStatement = connection.prepareStatement("select * from phoenix_krb")) {
            try (ResultSet resultSet = preparedStatement.executeQuery()) {
                while (resultSet.next()) {
                    System.out.println(resultSet.getString("content"));
                }
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
