For example, the {{submissionContext}} in RMAppImpl contains references to protocolbuffer objects and other items that probably aren't necessary to keep around once the application has completed. We could significantly reduce the memory footprint of the RM by releasing objects that are no longer necessary once an application completes. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
