>          Issue Type: Bug

> Currently any run time exception thrown in thrift metastore during the following operations is not getting sent to hive execution engine.
>  * grant/revoke role
>  * grant/revoke privileges
>  * create role
> This is because ThriftHiveMetastore just handles MetaException and throws TException during the processing of these requests.  So, the command just fails at thrift metastore end (Exception can be seen in metastore log) but the hive execution engine will keep on waiting for the response from thrift metatstore.
>  
> Steps to reproduce this problem :
> Launch thrift metastore
> Launch hive cli by passing --hiveconf hive.metastore.uris=thrift://127.0.0.1:10000 (pass the thrift metatstore host and port)
> Execute the following commands:
>  # set role admin
>  # create role test; (succeeds)
>  # create role test; ( hive version 2.1.1 : command is stuck, waiting for the response from thrift metastore; hive version 1.2.1: command fails with exception as null) 
>
