Subject [jira] [Created] (SPARK-24110) Avoid calling UGI loginUserFromKeytab in ThriftServer
Date Fri, 27 Apr 2018 07:05:00 GMT
Saisai Shao created SPARK-24110:

             Summary: Avoid calling UGI loginUserFromKeytab in ThriftServer
                 Key: SPARK-24110
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: Saisai Shao

Spark ThriftServer will call UGI.loginUserFromKeytab twice in initialization. This is unnecessary
and will cause various potential problems, like Hadoop IPC failure after 7 days, or RM failover
issue and so on.

So here we need to remove all the unnecessary login logics and make sure UGI in the context
never be created again.
