Sean Busbey commented on HBASE-11699:
-------------------------------------
bq. instead of having just an "allowedRS" table that stores just "booleans" why
not generalize it a bit as "rsSettings" or similar, that can be used in the
future to tune rs settings.. like how many regions can stay on that RS or
similar
Good idea, maybe generalize to "region_servers" instead of just settings? Maybe
then we could use it to build aggregate metrics for HBASE-11519?
> 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?
