nkeywal commented on HBASE-5682:
--------------------------------
In 0.96 this should work, with the restriction that the logic is that you can
get a non working connection, that will get fixed when you try to use it. It's
a different mechanism than the one for HBaseAdmin, as HBaseAdmin first check
the connection. Thz ZK mechanism is more efficient (you save a remote call to
check that the connection is really working), but is more complex.
However it seems it does not work at the end:
bq. What I saw in 0.96 is that the client was blocked for a very long time
(gave up after a few minutes), even though I had set all timeouts to low
values. This is also deadly in an app server setting. Might be a simple fix
there, didn't dig deeper.
@lars What did you exactly do? I can do the fix it on 0.96.
> 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)
