Subject [jira] [Commented] (FLINK-7860) Support YARN proxy user in Flink (impersonation)
Date Thu, 04 Jan 2018 01:39:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-7860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16310583#comment-16310583

Shuyi Chen commented on FLINK-7860:
-----------------------------------

Using the HADOOP_PROXY_USER env variable would be good for command line client submission,
but if we have a super service to programmatically submit jobs on behalf of users, switching
the env variable for different users would require extra locking to make sure that the setting
of the global HADOOP_PROXY_USER variable and submitting job are atomic. Adding a configuration
would easily solve the issue, as it's local. 

I think we can support both HADOOP_PROXY_USER (similar to [HIVE-15579 | https://issues.apache.org/jira/browse/HIVE-15579])
and an extra proxy user configuration, and the extra configuration take precedence. 

Also, we still need an extra configuration to specify the keytab path for the proxy user.
