-----------------------------------------------------------------
The unit test or the structure of the code likely needs to be modified -- I get
this when I try to run the test and this is likely due to the shutdown hook.

> Multiple invocations of hbck in parallel disables balancer permanently
> -----------------------------------------------------------------------
>
> Key: HBASE-11405
> URL: https://issues.apache.org/jira/browse/HBASE-11405
> Project: HBase
> Issue Type: Bug
> Components: Balancer, hbck
> Affects Versions: 0.99.0
> Reporter: bharath v
> Assignee: bharath v
> Attachments: HBASE-11405-trunk-rebased.patch,
> HBASE-11405-trunk.patch, HBASE-11405-trunk.patch.1
>
>
> This is because of the following piece of code in hbck
> {code:borderStyle=solid}
> boolean oldBalancer = admin.setBalancerRunning(false, true);
> try {
> onlineConsistencyRepair();
> }
> finally {
> admin.setBalancerRunning(oldBalancer, false);
> }
> {code}
> Newer invocations set oldBalancer to false as it was disabled by previous
> invocations and this disables balancer permanently unless its manually turned
> on by the user. Easy to reproduce, just run hbck 100 times in a loop in 2
> different sessions and you can see that balancer is set to false in the
> HMaster logs.
