Jian He commented on YARN-2790: ------------------------------- bq. it will keep on logging info about them for every localization and log-agregation for that app localization happens only once for each container and log-agregation happens only at the end of the regular app (or on log rolling interval). the sole reason is for easier debugging, I can change them to debug if you think it's an issue. bq. Seems like the system-credentials are never deleted even if the app finishes! Do you mean remove from RM ? DelegationTokenRenewer#removeApplicationFromRenewal does that. > NM can't aggregate logs past HDFS delegation token expiry. > ---------------------------------------------------------- > > Key: YARN-2790 > URL: https://issues.apache.org/jira/browse/YARN-2790 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 2.6.0 > Reporter: Tassapol Athiapinya > Assignee: Jian He > Attachments: YARN-2790.1.patch > > > We shorten hdfs delegation token lifetime, set RM to act as as a proxy user > in order to be able to renew the token on behalf of a user submitting the > application.
