Thanks, Peter > Removing stale Zookeeper locks at HiveServer2 initialization > ------------------------------------------------------------ > > Key: HIVE-14979 > URL: https://issues.apache.org/jira/browse/HIVE-14979 > Project: Hive > Issue Type: Improvement > Components: Locking > Reporter: Peter Vary > Assignee: Peter Vary > Attachments: HIVE-14979.patch > > > HiveServer2 could use Zookeeper to store token that indicate that particular > tables are locked with the creation of persistent Zookeeper objects. > A problem can occur when a HiveServer2 instance creates a lock on a table and > the HiveServer2 instances crashes ("Out of Memory" for example) and the locks > are not released in Zookeeper. This lock will then remain until it is > manually cleared by an admin. > There should be a way to remove stale locks at HiveServer2 initialization, > helping the admins life. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
