Nope. It seems Region normalizer sends request directly to RSRpcServices and has no idea about
HBASE-15128.  [~tedyu], can you double check that? cc: [~hengchu]

Another question on HBASE-15128:

Do HBase region balancer and catalog janitor have an idea about disabled splits/merges? Not
sure if they do splits/merges though.

 Upd: seems OK. RS report Master on every region state transition and Master allows or disallows
this transition? Correct?
