Subject [jira] [Commented] (YARN-2262) Few fields displaying wrong values in Timeline server after RM restart
Date Tue, 22 Jul 2014 07:49:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-2262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14069950#comment-14069950

Zhijie Shen commented on YARN-2262:
-----------------------------------

How's your setup for RM restarting? does the application continue after RM restarting? If
so, will the timeline server converge to show the missing fields correctly?

The wrong fields you saw here is because the finish information of the application is missing.
However,  let's say if the application is going on until being finished after RM restarting,
RM will still write the finish information, and the wrong values should be corrected finally.

One meta comment for this and YARN-2330: It would be great if you can help improving the generic
history service. On the other side, we're seeking migrating the generic history data to the
timeline store, as we've seen the limitations of the fs history store. If this is finalized,
we may not continue the support of this store. You can keep an eye on YARN-2033.
