[jira] [Created] (HIVE-6839) SetProcessor should propagate config changes to TezSessionState

Rajesh Balamohan created HIVE-6839:
--------------------------------------

             Summary: SetProcessor should propagate config changes to TezSessionState
                 Key: HIVE-6839
                 URL: https://issues.apache.org/jira/browse/HIVE-6839
             Project: Hive
          Issue Type: Bug
          Components: Tez
            Reporter: Rajesh Balamohan
            Priority: Critical


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"
