stack commented on HBASE-4128:
------------------------------
Our 0.90 build was using 'ubuntu' as host to build on. This could be more than
one machine. I changed it to be 'ubuntu2'. I also have the 0.90 build first
run some shell commands -- hostname, ulimit -a, and jps. We can see if any zk
running.
> Detect whether there was zookeeper ensemble hanging from previous build

> Project: HBase
> Issue Type: Task
> Reporter: Ted Yu
>
> Quite often, we see unit test(s) time out after 15 minutes.
> One example was TestShell:
> https://builds.apache.org/view/G-L/view/HBase/job/hbase-0.90/239/console
> This may be caused by zookeeper ensemble hanging from previous build.
> We should detect (and terminate, if possible) the hanging zk ensemble from
> previous build as the first step in current build.
