Lars Hofhansl commented on HBASE-5682:
--------------------------------------
Thanks Ted.
# the condition is different, because that is what it did before. I.e. if the
connection is managed the trackers are setup only at construction and during
abort in the specific case of SessionExpiredException. If the connection is
unmanaged on the other hand the trackers are rechecked before they are needed
and hence abort becomes a no-op for any KeeperExcepion. Hence the condition is
exactly reversed. This part is the key of the patch actually.
# The space wasn't there before. I actually had the space added and then
removed it again :) I'll add it back.

> 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)
