[jira] Updated: (ZOOKEEPER-886) Hedwig Server stays in disconnected state when connection to ZK dies but gets reconnected
[ https://issues.apache.org/jira/browse/ZOOKEEPER-886?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Benjamin Reed updated ZOOKEEPER-886: Hadoop Flags: [Reviewed] +1 good catch erwin! Hedwig Server stays in disconnected state when connection to ZK dies but gets reconnected --- Key: ZOOKEEPER-886 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-886 Project: Zookeeper Issue Type: Bug Components: contrib-hedwig Reporter: Erwin Tam Assignee: Erwin Tam Attachments: ZOOKEEPER-886.patch The Hedwig Server is connected to ZooKeeper. In the ZkTopicManager, it registers a watcher so that if it ever gets disconnected from ZK, it will temporarily fail all incoming requests since the Hedwig server does not know for sure if it is still the master for the topics. When the ZK client gets reconnected, the logic currently is wrong and it does not unset the suspended flag. Thus once it gets disconnected, it will stay in the suspended state forever, thereby making the Hedwig server hub dead. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
