Jian He commented on YARN-4087: ------------------------------- Right, we should make sure the state is correct if the error is ignored. Uploaded a new patch which addressed Vinod's comment about the inconsistent state. Also updated the description about the fixes included in this jira. > Followup fixes after YARN-2019 regarding RM behavior when state-store error > occurs > ---------------------------------------------------------------------------------- > > Key: YARN-4087 > URL: https://issues.apache.org/jira/browse/YARN-4087 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Jian He > Assignee: Jian He > Attachments: YARN-4087.1.patch, YARN-4087.2.patch, YARN-4087.3.patch > > > Several fixes: > 1. Set YARN_FAIL_FAST to be false by default, since this makes more sense in > production environment. > 2. Fixes state-store to also notify app/attempt if state-store error is > ignored so that app/attempt is not stuck at *_SAVING state > 3. If HA is enabled and if there's any state-store error, after the retry > operation failed, we always transition RM to standby state. Otherwise, we > may see two active RMs running. YARN-4107 is one example. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
