Allen Wittenauer resolved MAPREDUCE-392.
----------------------------------------
Resolution: Won't Fix
Sorry Doug, but I'm going to close this as Won't Fix because "Sometime we
default to re-usable JVMs, sometimes we don't!" makes the system slightly
unpredictable.
> streaming and pipes should reuse jvm's by default
> -------------------------------------------------
>
> Key: MAPREDUCE-392
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-392
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/streaming, pipes
> Reporter: Doug Cutting
>
> With HADOOP-249, tasks can now reuse JVMs. Pipes and streaming run little
> user code in their JVMs and should generally benefit from JVM reuse. Thus I
> propose we change the default for these to be JVM reuse.
