Karthik Kambatla commented on YARN-2962: ---------------------------------------- [~varun_saxena] - it will indeed be backwards incompatible. We should get this into trunk. To include this in branch-2, we should probably guard this with a config, and users will have to format the store to start using this. Otherwise, an RM restart will fail. > ZKRMStateStore: Limit the number of znodes under a znode > -------------------------------------------------------- > > Key: YARN-2962 > URL: https://issues.apache.org/jira/browse/YARN-2962 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.6.0 > Reporter: Karthik Kambatla > Assignee: Varun Saxena > Priority: Critical > > We ran into this issue where we were hitting the default ZK server message > size configs, primarily because the message had too many znodes even though > they individually they were all small. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
