---------------------------------------------------------
I am planning to have the information stored in meta table. I am looking into
the metatableaccessor and other relevant classes.
Probably the rowkey value will be combination of [ [prefix-partial-key]
[allow/deny] [hostname]], and there will be no value for this rowkey. I will
scan the included and excluded hosts information from this information. Let me
find out whether it will work.
> Region servers exclusion list to HMaster.

> 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?
