Jun Gong commented on YARN-4773: -------------------------------- Thanks [~jlowe] for confirming it. I will attach a patch to fix it if you are not working on it. > Log aggregation performs extraneous filesystem operations when rolling log > aggregation is disabled > -------------------------------------------------------------------------------------------------- > > Key: YARN-4773 > URL: https://issues.apache.org/jira/browse/YARN-4773 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 2.6.0 > Reporter: Jason Lowe > Priority: Minor > > I noticed when log aggregation occurs for an application the nodemanager is > listing the application's log directory in HDFS. Apparently this is for > removing old logs before uploading new ones. This is a wasteful operation > when rolling log aggregation is disabled, since there will be no prior logs > in HDFS -- aggregation only occurs once when rolling log aggregation is > disabled. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
