Jim Brennan created YARN-7678: --------------------------------- Summary: 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: 3.0.0, 2.8.0 Reporter: Jim Brennan Assignee: Jim Brennan
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
