[jira] [Created] (YARN-1395) Distributed shell application master launched with debug flag can hang waiting for external ls process.

Chris Nauroth created YARN-1395:
-----------------------------------

             Summary: Distributed shell application master launched with debug flag can hang waiting for external ls process.
                 Key: YARN-1395
                 URL: https://issues.apache.org/jira/browse/YARN-1395
             Project: Hadoop YARN
          Issue Type: Bug
          Components: applications/distributed-shell
    Affects Versions: 2.2.0, 3.0.0
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


Distributed shell launched with the debug flag will run {{ApplicationMaster#dumpOutDebugInfo}}.  This method launches an external process to run ls and print the contents of the current working directory.  We've seen that this can cause the application master to hang on {{Process#waitFor}}.
