It had many thousands of Mappers and thousands of > Reducers. It was noted that in the logging that the event-queue of > {{AsyncDispatcher}} had a very large number of item in it and was seemingly > never decreasing. > I started looking at the code and thought it could use some clean up, > simplification, and the ability to specify a bounded queue so that any > incoming events are throttled until they can be processed. This will protect > the ApplicationMaster from a flood of events. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
