Sean Busbey commented on HBASE-11699:
-------------------------------------
Keep in mind the impact of our [invariant on zookeeper
state|http://hbase.apache.org/book.html#design.invariants.zk.data] being
transient.
Presuming we'd want to persist this information across zookeeper wipes, where
could we persist this? Is the dataset small enough that a special file in HDFS
works? Should this be stored in a special table? Can we add it to META?
> 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

> Original Estimate: 96h
> Remaining Estimate: 96h

> 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?
