             Summary: Add a temporary configuration to YARNRunner to allow it to kill a session when a job is submitted
                 Key: TEZ-603
                 URL: https://issues.apache.org/jira/browse/TEZ-603
             Project: Apache Tez
          Issue Type: Task
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


Hive on Tez still uses MapReduce jobclient to submit jobs in certain cases. When a session is already running - this causes unnecessary resource contention.
It's far simpler for Tez to handle this task kill (avoid unnecessary shimming etc in Hive)This will be a temporary patch to allow YARNRunner to kill an existing session. To be reverted soon.
