> The Scenario can be reproduce below.
> Enabling an table, some region is online on regionserver,some are still being processed.
> And restart the master.
> when master failover:
>         // Region is being served and on an active server
>         // add only if region not in disabled and enabling table
>         if (false == checkIfRegionBelongsToDisabled(regionInfo)
>             && false == checkIfRegionsBelongsToEnabling(regionInfo)) {
>           regions.put(regionInfo, regionLocation);
>           addToServers(regionLocation, regionInfo);
>         }
> the opened region will not add to the Regions in master.
> and in the following recoverTableInEnablingState,the region will be assigned again.
> that will lead to the cluster inconsistent
