Devaraj K reassigned YARN-65: ----------------------------- Assignee: Devaraj K > Reduce RM app memory footprint once app has completed > ----------------------------------------------------- > > Key: YARN-65 > URL: https://issues.apache.org/jira/browse/YARN-65 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 0.23.3 > Reporter: Jason Lowe > Assignee: Devaraj K > > The ResourceManager holds onto a configurable number of completed > applications (yarn.resource.max-completed-applications, defaults to 10000), > and the memory footprint of these completed applications can be significant. > 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 (v6.3.4#6332)
