Tsuyoshi OZAWA reassigned YARN-1307: ------------------------------------ Assignee: Tsuyoshi OZAWA > Rethink znode structure for RM HA > --------------------------------- > > Key: YARN-1307 > URL: https://issues.apache.org/jira/browse/YARN-1307 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Tsuyoshi OZAWA > Assignee: Tsuyoshi OZAWA > > Rethink for znode structure for RM HA is proposed in some JIRAs(YARN-659, > YARN-1222). The motivation of this JIRA is quoted from Bikas' comment in > YARN-1222: > {quote} > We should move to creating a node hierarchy for apps such that all znodes for > an app are stored under an app znode instead of the app root znode. This will > help in removeApplication and also in scaling better on ZK. The earlier code > was written this way to ensure create/delete happens under a root znode for > fencing. But given that we have moved to multi-operations globally, this isnt > required anymore. > {quote} -- This message was sent by Atlassian JIRA (v6.1#6144)
