Hudson commented on YARN-7984: ------------------------------ SUCCESS: Integrated in Jenkins build Hadoop-trunk-Commit #13959 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/13959/]) YARN-7984. Improved YARN service stop/destroy and clean up.

The service AM does have some code to > clean up the registry entries when component instances are stopped, but if > the AM is killed before it has a chance to perform the cleanup, these entries > will be left in ZooKeeper. It would be better to clean these up in the stop > call, so that RegistryDNS does not provide lookups for containers that don't > exist. > Additional stop/destroy behavior improvements include fixing errors / > unexpected behavior related to: > * destroying a saved (not launched or started) service > * destroying a stopped service > * destroying a destroyed service > * returning proper exit codes for destroy failures > * performing other client operations on saved services (fixing NPEs) -- 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
