Description

Subprocess has problem when run in multithreaded environment. As stated by developers it should not be used in such env.
As a result Ambari done multiple patches to subprocess. However still we are having multithreading problems with it.

This jira targets moving from Subprocess to Subprocess32 (a port of Python3.0 subprocess) which support multithreaded execution.
