> If we have a  table in partially enabled state (ENABLING) then on HMaster restart we treat it as a clean cluster start up and do a bulk assign.  Currently in 0.94 bulk assign will not handle ALREADY_OPENED scenarios and it leads to region assignment problems.  Analysing more on this we found that we have better way to handle these scenarios.

> if (false == checkIfRegionBelongsToDisabled(regionInfo)
>             && false == checkIfRegionsBelongsToEnabling(regionInfo)) {
>           synchronized (this.regions) {
>             regions.put(regionInfo, regionLocation);
>             addToServers(regionLocation, regionInfo);
>           }
> {code}
> We dont add to regions map so that enable table handler can handle it.  But as nothing is added to regions map we think it as a clean cluster start up.
> Will come up with a patch tomorrow.
