Heng Chen commented on HBASE-15128:
-----------------------------------

mvn  -DHBasePatchProcess clean test-compile -DskipTests=true  could pass 
locally.
It seems QA compile hbase-server with old hbase-client.jar,   not sure why, 
[~busbey].

>
> In large clusters where region splits are frequent, and HBCK runs take 
> longer, the concurrent splits cause further problems in HBCK since HBCK 
> assumes a static state for the region partition map. We have just seen a case 
> where HBCK undo's a concurrently splitting region causing number of 
> inconsistencies to go up. 
> We can have a mode in master where splits and merges are disabled like the 
> balancer and catalog janitor switches. Master will reject the split requests 
> if regionservers decide to split. This switch can be turned on / off by the 
> admins and also automatically by HBCK while it is running (similar to 
> balancer switch being disabled by HBCK). 
> HBCK  should also disable the Catalog Janitor just in case.
