[jira] [Comment Edited] (HBASE-11699) Region servers exclusion list to HMaster.

    [ https://issues.apache.org/jira/browse/HBASE-11699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14093553#comment-14093553 ]

------------------------------------------------------------------

In the 'master' branch, we no longer have a separate HMaster process. One of the regionservers will be elected to also handle the HMaster function. How do you envision a file based exclusion list working in that type of environment?

> 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?
