Hitesh Shah commented on TEZ-550:
---------------------------------
[~bikassaha] Is this still valid? Are we looking for re-launching the jvms at
various points ( between DAGs, after certain re-use counts) via the container
lease concept in YARN or another wrapper script?
> Allow re-launching the child JVM in between dags

> Child JVM may leak memory or threads or statics etc. So it may make sense to
> use the idle time between dags to re-launch the JVMs.
