Jim Brennan updated YARN-7678: ------------------------------ Attachment: YARN-7678.001.patch Uploading patch for testing. Tested locally by running unit tests and enabling the new logger at DEBUG to ensure only the memory stats are logged. > Logging of container memory stats is missing in 2.8 > --------------------------------------------------- > > Key: YARN-7678 > URL: https://issues.apache.org/jira/browse/YARN-7678 > Project: Hadoop YARN > Issue Type: Improvement > Components: nodemanager > Affects Versions: 2.8.0, 3.0.0 > Reporter: Jim Brennan > Assignee: Jim Brennan > Attachments: YARN-7678.001.patch > > > YARN-3424 changed logging of memory stats from ContainersMonitorImpl to INFO > to DEBUG. > We have found these log messages to be useful information in Out-of-Memory > situations - they provide detail that helps show the memory profile of the > container over time, which can be helpful in determining root cause. > Here's an example message from YARN-3424: > {noformat} > 2015-03-27 09:32:48,905 INFO > org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainersMonitorImpl: > Memory usage of ProcessTree 9215 for container-id > container_1427462602546_0002_01_000008: 189.8 MB of 1 GB physical memory > used; 2.6 GB of 2.1 GB virtual memory used > {noformat} > Propose to change this to use a separate logger for this message, so that we > can enable debug logging for this without enabling all of the other debug > logging for ContainersMonitorImpl. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
