Jesse Yates commented on HBASE-6110:
------------------------------------
Back to the real issue, it seems like a concurrency bug, like surefire isn't
doing the right then when parallelizing the tests. There is the fork factor of
4 (perThread and then threads set to 4). Originally, this was done in
HBASE-5064; I'm surprised that we didn't break things there. Conceptually, the
parallelization shouldn't work unless we get consistently lucky with test order
- the minicluster will have problems if it can't find the right port, which it
shouldn't if another jvm is also running a mini-cluster.
The this wouldn't be a big issue except that the master goes down if the http
server port is already taken:

Should this be the case? I feel like hbasetestutility's minicluster should have
the webui off by default, unless otherwise desired (I tend to turn it off in
the tests I write, just to speed things up). Also, if the webui is taken, it
should just bump the port number to the next available.
Thoughts?
