> consider such Scenario:
> we have a table called T1, which has 1 regions: A 
> 1. move A from rs1 to rs2,and A is now closed
> 2. disable T1,
> 3. delete  T1.
> when we disable T1, disable handler will just set the zk to disabled and A will still be assigned. when Ais opened, A in transition will be clean out. 
> At that time, Deletetable found it is safe to delete all regions and table in meta and fs , it will also delete the zk node of T1.
> while (System.currentTimeMillis() < done) {
>         AssignmentManager.RegionState rs = am.isRegionInTransition(region);
>         if (rs == null) break;
>         Threads.sleep(waitingTimeForEvents);
>         LOG.debug("Waiting on  region to clear regions in transition; " + rs);
>       }
>       if (am.isRegionInTransition(region) != null) {
>         throw new IOException("Waited hbase.master.wait.on.region (" +
>           waitTime + "ms) for region to leave region " +
>           region.getRegionNameAsString() + " in transitions");
>       }
> howover A is still being unassigned, when it finished closed the A,it finds that the disabled state in zk is deleted, and then A will be assigned again.
