-------------------------------------
bq. Another reason for having it is that without HA, we have it, so this at
least keeps things consistent.
okay.
> ZKLocksService instrumentation should say how many locks this server has

> Project: Oozie
> Issue Type: Improvement
> Components: HA
> Affects Versions: trunk
> Reporter: Robert Kanter

> Attachments: OOZIE-1801.patch

>
> The MemoryLocksService has a variable named "locks" under the "locks" group
> in the instrumentation that reports how many locks are currently acquired.
> When using Oozie HA, we don't have this.
> We shouldn't have it report the total number of locks acquired by all Oozie
> servers because that would require checking ZooKeeper every time we check
> this. However, reporting the number of locks acquired by _this_ Oozie server
> should be inexpensive while still being helpful and similar to the non-HA
> behavior.
