Varun Saxena created YARN-2432: ---------------------------------- Summary: RMStateStore should process the pending events before close Key: YARN-2432 URL: https://issues.apache.org/jira/browse/YARN-2432 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Reporter: Varun Saxena Assignee: Varun Saxena
Refer to discussion on YARN-2136 (https://issues.apache.org/jira/browse/YARN-2136?focusedCommentId=14097266&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14097266). As pointed out by [~jianhe], we should process the dispatcher event queue before closing the state store by flipping over the following statements in code. {code:title=RMStateStore.java|borderStyle=solid} protected void serviceStop() throws Exception { closeInternal(); dispatcher.stop(); } {code} Currently, if the state store is being closed on events such as switching to standby, it will first close the state store(in case of ZKRMStateStore, close connection with ZK) and then process the pending events. Instead, we should first process the pending events and then call close. -- This message was sent by Atlassian JIRA (v6.2#6252)
