                 Key: AMBARI-22953
                 URL: https://issues.apache.org/jira/browse/AMBARI-22953
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.6.2
         Attachments: AMBARI-22953.patch

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.
