Brock Noland commented on HIVE-6082: ------------------------------------ +1 > 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 > Assignee: Chaoyu Tang > Attachments: HIVE-6082.patch, Hive-6082.patch > > > 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 (v6.1.5#6160)
