> When "hive.execution.engine=tez" is enabled, hive cli launches a tez session.  But any config changes via "set" command is not propagated to TezSessions.  
> E.g 
> 1. hive --hiveconfig hive.execution.engine=tez
> 2. set tez.runtime.io.sort.mb = 1024;
> 3. set tez.runtime.io.sort.mb (//to verify if the parameter is set)
> 4. Run a hive query and check the app logs.  It would not reflect 1024 for  "tez.runtime.io.sort.mb"
