Bikas Saha commented on YARN-1027: ---------------------------------- + // TODO (YARN-1192): Update this post addition of STOPPING state to Is this still needed since I see that HADOOP-9945 is already committed? Changes look good to me. Will wait for some time for other folks to take a look. Looks like not all the memory was reclaimed upon Active->Standby. One thing to check would be if the memory keeps increasing after every transition for multiple transitions. Another thing would be if the increase is proportional to the original memory. Given that the RM was at ~30MB, 3MB might end up being noise. E.g. there might be a lot of node state that leaks but the job state is GC'd (so large clusters will show bad leaks). OR it might be that job state leaks but node state gets deleted (so long running RM restart will show bad leaks). > Implement RMHAProtocolService > ----------------------------- > > Key: YARN-1027 > URL: https://issues.apache.org/jira/browse/YARN-1027 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Bikas Saha > Assignee: Karthik Kambatla > Attachments: test-yarn-1027.patch, yarn-1027-1.patch, > yarn-1027-2.patch, yarn-1027-3.patch, yarn-1027-4.patch, yarn-1027-5.patch, > yarn-1027-6.patch, yarn-1027-7.patch, yarn-1027-7.patch, yarn-1027-8.patch, > yarn-1027-including-yarn-1098-3.patch, yarn-1027-in-rm-poc.patch > > > Implement existing HAServiceProtocol from Hadoop common.
