Anoop Sam John commented on HBASE-16803:
----------------------------------------
I forgot the jira. But that is about having millions of regions. I believe it
originated from Y guys.
The current patch need addition of isAclTable() to HRegionInfo which is why I
prefer having the policy set. And see in case of vis labels, we do same. See
in VisibilityController.

> HBASE-16773 fixed a case where PriorityRpcServer handler threads are all
> occupied accessing hbase:acl table.
> However, the fix relies on the fact that there is single region in hbase:acl
> table so that the access can be local.
> As discussed at the end of HBASE-16773, we should disable split of hbase:acl
> table as well.
> hbase:meta is normally much larger than hbase:acl table and it has only one
> region.
