Akira Ajisaka commented on YARN-4946: ------------------------------------- This issue has been reverted from trunk, branch-3.3, and branch-3.2. This feature is in only 3.2.0 and 3.2.1. > RM should not consider an application as COMPLETED when log aggregation is > not in a terminal state > -------------------------------------------------------------------------------------------------- > > Key: YARN-4946 > URL: https://issues.apache.org/jira/browse/YARN-4946 > Project: Hadoop YARN > Issue Type: Improvement > Components: log-aggregation > Affects Versions: 2.8.0 > Reporter: Robert Kanter > Assignee: Szilard Nemeth > Priority: Major > Fix For: 3.2.0 > > Attachments: YARN-4946.001.patch, YARN-4946.002.patch, > YARN-4946.003.patch, YARN-4946.004.patch > > > MAPREDUCE-6415 added a tool that combines the aggregated log files for each > Yarn App into a HAR file. When run, it seeds the list by looking at the > aggregated logs directory, and then filters out ineligible apps. One of the > criteria involves checking with the RM that an Application's log aggregation > status is not still running and has not failed. When the RM "forgets" about > an older completed Application (e.g. RM failover, enough time has passed, > etc), the tool won't find the Application in the RM and will just assume that > its log aggregation succeeded, even if it actually failed or is still running. > We can solve this problem by doing the following: > The RM should not consider an app to be fully completed (and thus removed > from its history) until the aggregation status has reached a terminal state > (e.g. SUCCEEDED, FAILED, TIME_OUT). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
