[jira] [Updated] (YARN-1641) ZK store should attempt a write periodically to ensure it is still Active
[ https://issues.apache.org/jira/browse/YARN-1641?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Karthik Kambatla updated YARN-1641: --- Attachment: yarn-1641-2.patch Added thread name. ZK store should attempt a write periodically to ensure it is still Active - Key: YARN-1641 URL: https://issues.apache.org/jira/browse/YARN-1641 Project: Hadoop YARN Issue Type: Sub-task Components: resourcemanager Affects Versions: 2.3.0 Reporter: Karthik Kambatla Assignee: Karthik Kambatla Attachments: yarn-1641-1.patch, yarn-1641-2.patch Fencing in ZK store kicks in when the RM tries to write something to the store. If the RM doesn't write anything to the store, it doesn't get fenced and can continue to assume being the Active. By periodically writing a file (say, every RM_ZK_TIMEOUT_MS seconds), we can ensure it gets fenced. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
