Gopal V resolved TEZ-1250.
--------------------------
Resolution: Not a Problem
min-held containers fix is more recent development, which offers a better
alternative to this.
> 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.
