Jason Lowe updated MAPREDUCE-4517: ---------------------------------- Attachment: MAPREDUCE-4517.patch Patch to only log scheduling stats when they change. > Too many INFO messages written out during AM to RM heartbeat > ------------------------------------------------------------ > > Key: MAPREDUCE-4517 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4517 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: applicationmaster > Affects Versions: 0.23.1, 2.0.1-alpha > Reporter: James Kinley > Priority: Minor > Labels: patch > Attachments: MAPREDUCE-4517.patch, MAPREDUCE-4517.patch > > > Too many INFO log messages written out during AM to RM heartbeat. Based on > default frequency of 1000ms (scheduler.heartbeat.interval-ms) either 2 or 4 > INFO messages are written out per second: > LOG.info("Before Scheduling: " + getStat()); > List<Container> allocatedContainers = getResources(); > LOG.info("After Scheduling: " + getStat()); > if (allocatedContainers.size() > 0) { > LOG.info("Before Assign: " + getStat()); > scheduledRequests.assign(allocatedContainers); > LOG.info("After Assign: " + getStat()); > } > These should probably be changed to DEBUG message to save the log growing too > quickly. -- This message is automatically generated by JIRA.
