Chaoyu Tang created HIVE-6082: --------------------------------- Summary: Certain KeeperException should be ignored in ZooKeeperHiveLockManage.unlockPrimitive Key: HIVE-6082 URL: https://issues.apache.org/jira/browse/HIVE-6082 Project: Hive Issue Type: Bug Affects Versions: 0.12.0 Reporter: Chaoyu Tang
KeeperException.NoNodeException and NotEmptyException should be ignored when deleting a zLock or its parent in ZooKeeperHiveLockManager unlockPrimitive. The exceptions can happen: 1) ZooKeeperHiveLockManager retries deleting a zLock after a failure but it has been deleted. 2) a race condition where another process adds a zLock just before it is about to be deleted. Otherwise, unlock may unnecessarily be retried for numRetriesForUnLock times. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
