Subject [jira] [Created] (AMBARI-16217) Command execution by single python executor.

Sebastian Toader created AMBARI-16217:
-----------------------------------------

             Summary: Command execution by single python executor.
                 Key: AMBARI-16217
                 URL: https://issues.apache.org/jira/browse/AMBARI-16217
             Project: Ambari
          Issue Type: Task
          Components: ambari-server
            Reporter: Sebastian Toader
             Fix For: 2.4.1


Currently, all commands are executed via own python executor - either serially or in parallel.
Instead, a single python executor can be created to execute all commands. When all commands
are combined, then one execution of before-install/start and after-install/start would suffice.
In addition, all starts can be called in parallel while configure can be serialized where
there are shared resources.
