Gergo Repas commented on YARN-5028: ----------------------------------- [~yufeigu] - Right, the null check can be abandoned (I'll upload a new patch when the rest of the questions are cleared). Regarding your second question: I'm using a new instance to trim down the state as much as possible (also, I had to provide a non-null reference, otherwise an exception is thrown at the line you quoted from createAndPopulateNewRMApp()). > RMStateStore should trim down app state for completed applications > ------------------------------------------------------------------ > > Key: YARN-5028 > URL: https://issues.apache.org/jira/browse/YARN-5028 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 2.8.0 > Reporter: Karthik Kambatla > Assignee: Gergo Repas > Priority: Major > Attachments: YARN-5028.000.patch, YARN-5028.001.patch, > YARN-5028.002.patch > > > RMStateStore stores enough information to recover applications in case of a > restart. The store also retains this information for completed applications > to serve their status to REST, WebUI, Java and CLI clients. We don't need all > the information we store today to serve application status; for instance, we > don't need the {{ApplicationSubmissionContext}}. -- 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
