-------------------------------------
Summary: When kerbero authentication is enabled, hadoop_ Proxy
cannot take effect.
Key: FLINK-31295
URL: https://issues.apache.org/jira/browse/FLINK-31295
Project: Flink
Issue Type: Bug
Reporter: HunterXHunter
When I set ：
security.kerberos.login.keytab: kerbero_user.keytab
security.kerberos.login.principal: kerbero_user
and set HADOOP_PROXY_USER = proxy_user
Data is still written to hdfs as user kerbero_user.
But :
When I turn off kerbero authentication. data is written to hdfs as user
proxy_user.
Finally, I found the logic in HadoopModule#install would not be used as a
hadoop proxy when kerbero authentication is enabled.
