> 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
> Fix For: 2.0.0, 0.99.1
>
> Attachments: 11405-v3.txt, 11405-v5.patch, 11405-v6.patch,
> HBASE-11405-trunk-rebased.patch, HBASE-11405-trunk.patch,
> HBASE-11405-trunk.patch.1, hbase-11405.rebase.140911.patch
>
>
> 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.
