> 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.
