Gomathivinayagam Muthuvinayagam commented on HBASE-11699:
---------------------------------------------------------

Sure, I will change that. Currently I added region_servers table as default 
table. This means, I need to change the test case, where it tests for expected 
no of system tables as 2(namespace, and meta), so I have to change the test 
cases by changing it as 3. Is this a good approach? or I can make this table to 
get loaded on adding some configuration in the xml file. What do you guys think 
on that? [~busbey] [~mbertozzi]

> Currently HBase does not support adding set of region servers to be in the 
> exclusion list. So that administrators can prevent accidental startups of 
> some region servers to join the cluster. There was initially some work done, 
> and it is available in https://issues.apache.org/jira/browse/HBASE-3833. It 
> was not done after that. 
> I am planning to contribute it as a patch, and I would like to do some 
> improvements as well. Instead of storing the exclusion entries on a file, I 
> am planning to store it on zookeeper. Can anyone suggest thoughts on this?
