Subject [jira] [Updated] (YARN-7275) NM Statestore cleanup for Container updates
Date Fri, 13 Oct 2017 17:35:01 GMT

     [ https://issues.apache.org/jira/browse/YARN-7275?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

kartheek muthyala updated YARN-7275:
    Attachment: YARN-7275.005.patch

[~asuresh], Can you please review the following updated patch for YARN-7275.
It contains the following changes:
1.	Introduced RECOVERY_COMPLETED, containerscheduler event for trying queued recovered containers.
2.	Introduced RECOVER_CONTAINER_PAUSED event in ContainerEvents for moving the container that
was recovered as paused from scheduled -> PAUSED after we initialize the containerimpl
object for it.
3.	Reused the existing event – ContainersLauncherEventType.RECOVER_CONTAINER_PAUSED for
reacquiring paused container, instead of failing.

+ earlier patch that you are aware of. The changes only take care of recovered containers
that were paused. For containers which has moved to SCHEDULED, but didn’t get a chance to
run to RUNNING, the state in which they will be recovered is REQUESTED, hence ultimately they
will be retried from the queue of ContainerScheduler.

Let me know if the changes seems okay.
