Subject [jira] [Created] (HBASE-11699) Region servers exclusion list to HMaster.
Date Thu, 07 Aug 2014 21:27:15 GMT
Gomathivinayagam Muthuvinayagam created HBASE-11699:
-------------------------------------------------------

             Summary: Region servers exclusion list to HMaster.
                 Key: HBASE-11699
                 URL: https://issues.apache.org/jira/browse/HBASE-11699
             Project: HBase
          Issue Type: New Feature
          Components: Admin, Client, regionserver, Zookeeper
    Affects Versions: 0.98.3
            Reporter: Gomathivinayagam Muthuvinayagam
            Priority: Minor
             Fix For: 0.98.3


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?
