[jira] [Created] (AMBARI-22473) shell.process_executor races process exit

Jonathan Matthew created AMBARI-22473:
-----------------------------------------

             Summary: shell.process_executor races process exit
                 Key: AMBARI-22473
                 URL: https://issues.apache.org/jira/browse/AMBARI-22473
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 2.6.0
            Reporter: Jonathan Matthew


By calling cmd.poll(), shell.process_executor assumes that the subcommand will have exited once it has finished reading from its stdout pipe. This isn't necessarily the case, so it should call cmd.wait() instead.
