----------------------------------

             Summary: .sparkStaging not clean on error
                 Key: SPARK-18027
                 URL: https://issues.apache.org/jira/browse/SPARK-18027
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.6.0
            Reporter: David Shar


Hi,

It seems that SPARK-7705 didn't fix all issues with .sparkStaging folder cleanup.

in Client.scala:monitorApplication 
{code}
 val report: ApplicationReport =
        try {
          getApplicationReport(appId)
        } catch {
          case e: ApplicationNotFoundException =>
            logError(s"Application $appId not found.")
            return (YarnApplicationState.KILLED, FinalApplicationStatus.KILLED)
          case NonFatal(e) =>
            logError(s"Failed to contact YARN for application $appId.", e)
            return (YarnApplicationState.FAILED, FinalApplicationStatus.FAILED)
        }
....
if (state == YarnApplicationState.FINISHED ||
        state == YarnApplicationState.FAILED ||
        state == YarnApplicationState.KILLED) {
        cleanupStagingDir(appId)
        return (state, report.getFinalApplicationStatus)
 }
{code}

In case of ApplicationNotFoundException, we don't cleanup the sparkStaging folder.

I believe we call cleanupStagingDir(appId) on the catch clause above.
