[jira] [Created] (TEZ-1250) Prevent timeouts for pre-warmed containers

Gopal V created TEZ-1250:
----------------------------

             Summary: Prevent timeouts for pre-warmed containers
                 Key: TEZ-1250
                 URL: https://issues.apache.org/jira/browse/TEZ-1250
             Project: Apache Tez
          Issue Type: Improvement
    Affects Versions: 0.5.0
         Environment: HS2 + default sessions + pre-warm DAG run
            Reporter: Gopal V


To prevent unnecessary delays for queries, pre-warmed containers should not be released by the AppMaster even if the containers have been idle for longer than the session delay is set to.

This will provide some sort of elasticity when using a low timeout, to grow and shrink between the prewarm min and the queue max.
