Bibin A Chundatt commented on YARN-8418: ---------------------------------------- Thank you [~rohithsharma] for review {quote}Why does token changed? It should be same during lifespan of application right? IIUC, token will be renewed but not going to be changed right? {quote} Delegation token what we are talking about has a life span of 7 days (max-life time) . So after 7 days we get new token. Also for application that doesnt provide delegation token, RM will generate one for user based on proxy enabled flag. {{RMDelegationTokenRenewer}} {quote} stale applications i.e which are completed from RM. In this case, token could be cancelled before NM removes from its statestore which could lead problem {quote} Incase of application completed at RM. NodeStatus heartbeat response we do fire application finish event rt ?? So Application finish should trigger -> Log aggregation StopApp ->which should stop the Aggregator thread too. So you think that is not happening ? > App local logs could leaked if log aggregation fails to initialize for the app > ------------------------------------------------------------------------------ > > Key: YARN-8418 > URL: https://issues.apache.org/jira/browse/YARN-8418 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.8.0, 3.0.0-alpha1 > Reporter: Bibin A Chundatt > Assignee: Bibin A Chundatt > Priority: Critical > Attachments: YARN-8418.001.patch, YARN-8418.002.patch, > YARN-8418.003.patch, YARN-8418.004.patch, YARN-8418.005.patch, > YARN-8418.006.patch, YARN-8418.007.patch, YARN-8418.008.patch > > > If log aggregation fails init createApp directory container logs could get > leaked in NM directory > For log running application restart of NM after token renewal this case is > possible/ Application submission with invalid delegation token -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
