stack updated HBASE-3074:
-------------------------
Attachment: 3074.txt
Tests were sharing an HCM. First test was expiring it. HCMs were proceeding
though ZKW had expired; was just serving stale data. On expiration, the HCM
actually gets an abort but we do nothing but log currently. Now we'll set an
actually unused 'closed' flag.
The first TZ test was also doing nothing. Changed it to assert connection
closed. Also corralled this session expiring test making sure the connection
used herein will not be used elsewhere (by making a new Configuration instance).
I'm going to commit. Hopefully fixes ZK up on hudson. MIght break something
else though, but probably something we want to break because its reliant on
flakey stale data to run.
