Bikas Saha commented on TEZ-550:
--------------------------------
Probably a wrapper script. Though YARN release may also work (though not
guaranteed to get same location etc). Good thing with wrapper script would be
ability to reuse any off-heap memory that was used on that machine. Good thing
with YARN release is that someone else may be able to use that machine.
Doing this enables us to get rid of leaks/statics and also general clean up
that may prevent a full blown GC in a subsequent reuse.
> 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.
