Jean-Daniel Cryans commented on HBASE-6273:
-------------------------------------------

I think we should have two exceptions:

- MasterNotRunning (you can contact the machine, but you get a connection refused and maybe I'd include PleaseHoldException)
- MasterUnreachable (Unknown host, EOF, and probably other IOEs)

This will really help operability, it happened a couple of time on the mailing list that someone would say "I got MasterNotRunning but it's running I can use it" when all they had was a connectivity issue.

I'd prefer we don't do this for a point release.
