I've been trying to play with locks in hive using zookeeper but can't
find documentation on how to configure it. I now have:
<property>
<name>hive.supports.concurrency</name>
<value>true</value>
</property>

<property>
<name>hive.zookeeper.quorum</name>
<value>localhost</value>
</property>

But I keep getting errors like this:

11/09/07 15:47:57 ERROR exec.DDLTask: FAILED: Error in metadata: show
Locks LockManager not specified
org.apache.hadoop.hive.ql.metadata.HiveException: show Locks LockManager

Any idea what I'm doing wrong?

Somewhere lower in my config file I set a incorrect LockManager so now
it works :)
