>
> 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.
