Subject [jira] [Commented] (YARN-5094) some YARN container events have timestamp of -1
Date Thu, 01 Jun 2017 23:11:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-5094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16033890#comment-16033890

Li Lu commented on YARN-5094:
-----------------------------

Sorry about the delay. Please feel free to take it. Let's not touch AbstractEvent as a whole
but treat different events separately? Also, even for NM related events we should be careful
about the actual performance. I barely remember that my last conclusion (a year ago) was it's
fine (to assign a timestamp for NM events), but let's be careful.

> Some events in the YARN container entities have timestamp of -1. The RM-generated container
events have proper timestamps. It appears that it's the NM-generated events that have -1:
YARN_CONTAINER_CREATED, YARN_CONTAINER_FINISHED, YARN_NM_CONTAINER_LOCALIZATION_FINISHED,
YARN_NM_CONTAINER_LOCALIZATION_STARTED.
> In the YARN container page,
> {noformat}
> {
> id: "YARN_CONTAINER_CREATED",
> timestamp: -1,
> info: { }
> },
> {
> id: "YARN_CONTAINER_FINISHED",
> timestamp: -1,
> info: {
> YARN_CONTAINER_EXIT_STATUS: 0,
> YARN_CONTAINER_STATE: "RUNNING",
> YARN_CONTAINER_DIAGNOSTICS_INFO: ""
> }
> },
> {
> id: "YARN_NM_CONTAINER_LOCALIZATION_FINISHED",
> timestamp: -1,
> info: { }
> },
> {
> id: "YARN_NM_CONTAINER_LOCALIZATION_STARTED",
> timestamp: -1,
> info: { }
> }
> {noformat}
> I think the data itself is OK, but the values are not being populated in the REST output?
