[jira] [Commented] (OOZIE-3512) Flaky test TestActionStartXCommand.testActionWithEscapedStringAndCDATA

    [ https://issues.apache.org/jira/browse/OOZIE-3512?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16890154#comment-16890154 ] 

Peter Bacsko commented on OOZIE-3512:
-------------------------------------

Usually an application stays in ACCEPTED state if there are not enough resources (vcores / memory). Another problem is when a node manager becomes UNHEALTHY - we set up the Mini YARN cluster with a single NM cluster, so if that happens, we can't run any applications. This happened many times before due to disk space issues and the disk checker, having detected a low amount of free space, marked the NM as "unhalthy" so we ended up with 0 NMs. But this was addressed and the threashold was raised to 99% or 100%. Anyway I'd examine the RM or NM output from the Mini cluster to see why this wasn't scheduled.
