Description

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.
