Ankit Kumar reassigned YARN-10537: ---------------------------------- Assignee: Ankit Kumar > Change type of LogAggregationService threadPool > ----------------------------------------------- > > Key: YARN-10537 > URL: https://issues.apache.org/jira/browse/YARN-10537 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Xie YiFan > Assignee: Ankit Kumar > Priority: Minor > > Now, LogAggregationService threadPool is FixedThreadPool which of default > threadPoolSize is 100. LogAggregationService will construct AppLogAggregator > for new come application and submit to threadPool. AppLogAggregator do while > loop unitl application finished. Some application may run very long time due > to reason such as no enough resource or other. As result, it occupy one > thread of threadPool. When this application size greater than threadPoolSize, > the later short-live application can't upload logs until previous long-live > application finished. So, i think we should replace FixedThreadPool to > CachedThreadPool. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
