Subject [jira] [Commented] (YARN-4597) Add SCHEDULE to NM container lifecycle
Date Tue, 08 Nov 2016 22:54:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-4597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15649082#comment-15649082

Jian He commented on YARN-4597:
-------------------------------

I see.. thanks for looking into it.. I guess the killedBeforeStart flag could be avoided,
by calling  "container.isMarkedToKill()" directly in the handleContainerExitCode method like
below ?
{code}
      if (!container.isMarkedToKill()) {
        dispatcher.getEventHandler().handle(
            new ContainerExitEvent(containerId,
                ContainerEventType.CONTAINER_KILLED_ON_REQUEST, exitCode,
                diagnosticInfo.toString()));
      }
{code}

> Currently, the NM immediately launches containers after resource localization. Several
features could be more cleanly implemented if the NM included a separate stage for reserving
resources.
