> Key: HIVE-12544
> URL: https://issues.apache.org/jira/browse/HIVE-12544
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 1.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
>
> When lock acquisition times out, it would be useful to include info in the
> message about the lock that caused the current request to block.
> It will help identify runaway processes, etc.
> This would require a Thrift change to pass that info up to the client which
> determines when to give up waiting.
> Implementation:
>
> In _case WAIT:_ in _TxnHandler.checkLock()_ add to
> _org.apache.hadoop.hive.metastore.api.LockResponse_ info from
> {code}locks[i]{code} which already has the ids and human readable info about
> conflicting lock.
