Lars Hofhansl commented on HBASE-5682:
--------------------------------------
Presumably close it not needed since the connection is known to be down in this
case. To be save, I'll add that, and make sure it doesn't cause another hang.
I think this is better than HBASE-5153, because it attempts to reconnect when
the connection is needed and not when it was lost (in which case it is likely
that the next retry will fail as well, leading to long hangs with no change for
the caller to notice).
> Allow HConnectionImplementation to recover from ZK connection loss (for 0.94

> Just realized that without this HBASE-4805 is broken.
> I.e. there's no point keeping a persistent HConnection around if it can be
> rendered permanently unusable if the ZK connection is lost temporarily.
> Note that this is fixed in 0.96 with HBASE-5399 (but that seems to big to
> backport)
