yunjiong zhao commented on YARN-6285: ------------------------------------- YARN-6339 is not applied to our cluster yet. When I create YARN-6285, what I want is a simple patch which allow us to control the GC ASAP. With YARN-6339, I believe we can set yarn.resourcemanager.max-limit-get-applications with a bigger value or not need set a limit any more. Will let you know after YARN-6339 pasted review and applied in our cluster. > Add option to set max limit on ResourceManager for > ApplicationClientProtocol.getApplications > -------------------------------------------------------------------------------------------- > > Key: YARN-6285 > URL: https://issues.apache.org/jira/browse/YARN-6285 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: yunjiong zhao > Assignee: yunjiong zhao > Attachments: YARN-6285.001.patch, YARN-6285.002.patch, > YARN-6285.003.patch > > > When users called ApplicationClientProtocol.getApplications, it will return > lots of data, and generate lots of garbage on ResourceManager which caused > long time GC. > For example, on one of our RM, when called rest API " http://<rm http > address:port>/ws/v1/cluster/apps" it can return 150MB data which have 944 > applications. > getApplications have limit parameter, but some user might not set it, and > then the limit will be Long.MAX_VALUE. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
