> Subprocess has problem when run in multithread environment. As stated by developers it should not be used in such an env.
> As a result Ambari done multiple patches to subprocess. However still we are having multithread problems with it.
> This jira targets moving from Subprocess to Subprocess32 (a port of Python3.0 subprocess) which support multithreaded execution.
