[jira] [Created] (SPARK-24110) Avoid calling UGI loginUserFromKeytab in ThriftServer

Saisai Shao created SPARK-24110:
-----------------------------------

             Summary: Avoid calling UGI loginUserFromKeytab in ThriftServer
                 Key: SPARK-24110
                 URL: https://issues.apache.org/jira/browse/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.
