yunjiong zhao created YARN-6339: ----------------------------------- Summary: Improve performance for createAndGetApplicationReport Key: YARN-6339 URL: https://issues.apache.org/jira/browse/YARN-6339 Project: Hadoop YARN Issue Type: Improvement Reporter: yunjiong zhao Assignee: yunjiong zhao
There are two performance issue when calling createAndGetApplicationReport: One is inside ProtoUtils.convertFromProtoFormat, replace is too slow for clusters which have more than 3000 nodes. Use substring is much better: https://issues.apache.org/jira/browse/YARN-6285?focusedCommentId=15923241&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15923241 Another one is inside getLogAggregationReportsForApp, if some application's LogAggregationStatus is TIME_OUT, every time it was called it will create an HashMap which will produce lots of garbage. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
