>                 Key: HADOOP-4601
>                 URL: https://issues.apache.org/jira/browse/HADOOP-4601
>             Project: Hadoop Core
>          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.
