Rohith Sharma K S commented on YARN-4953: ----------------------------------------- cc :/ [~jlowe] > Delete completed container log folder when rolling log aggregation is enabled > ----------------------------------------------------------------------------- > > Key: YARN-4953 > URL: https://issues.apache.org/jira/browse/YARN-4953 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Reporter: Rohith Sharma K S > Assignee: Rohith Sharma K S > > There would be potential bottle neck when cluster is running with very large > number of containers on the same NodeManager for single application. The > linux limits the subfolders count to 32K. If number of containers is greater > than 32K for an application, there would be container launch failure. At this > point of time, there are no more containers can be launched in this node. > Currently log folders are deleted after app is finished. Rolling log > aggregation aggregates logs to hdfs periodically. > I think if aggregation is completed for finished containers, then clean up > can be done i.e deleting log folder for finished containers. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
