> Currently only the count of regions in transition is exposed thru JMX.
> Here is a sample snippet of the /jmx output:
> {code}
> {
>   "beans" : [ {
> ...
>   }, {
>     "name" : "Hadoop:service=HBase,name=Master,sub=AssignmentManager",
>     "modelerType" : "Master,sub=AssignmentManager",
>     "tag.Context" : "master",
> ...
>     "ritCount" : 3
> {code}
> It would be desirable to expose region name, state for the regions in transition as well.
> We can place configurable upper bound on the number of entries returned in case there're a lot of regions in transition.
