Zach York commented on HBASE-18775:
-----------------------------------
Sorry for the delay, I was out for a bit. I'll be resuming work on this shortly.
[~ashish singhi] I didn't consider snapshots because they aren't as common for
our use case, but it is an interesting point. Should snapshots be disabled? I
looked into the code and it looks pretty easy to do that. Do you think
conceptually it makes sense to disable them on read replica clusters?
[~stack] I did some investigation and I agree that we can get rid of the
'global' keyword and just use hbase.readonly. I'll implement that and your
other suggestions and put up another diff.
