------------------------------------------------------------------
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?
