Subject [jira] [Commented] (YARN-1885) RM may not send the app-finished signal after RM restart to some nodes where the application ran before RM restarts
Date Sat, 14 Jun 2014 00:42:03 GMT

    [ https://issues.apache.org/jira/browse/YARN-1885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14031369#comment-14031369
] 

Wangda Tan commented on YARN-1885:
----------------------------------

[~jianhe],
bq. For nodes that expired but rejoin with earlier running applications, if the application
by this time has completed, I think we should also send the app-finished signal ?
This is behavior in existing patch.

> During our HA testing we have seen cases where yarn application logs are not available
through the cli but i can look at AM logs through the UI. RM was also being restarted in the
background as the application was running.
