Vishal,

the test failures you are seeing?
thanks

Urg. Ben can you create a subtask off 1157 for this? List the tests
which are effected.
fwiw on my CI setup I'm not currently seeing random failures on tests
- although I have seen this when:
1) when running multiple slots on a Jenkins host and running both
hadoop (or hbase, etc...) unit tests at the same time as running ZK
unit tests
2) when running with insufficient ulimits

i've looked into this a bit. it looks like a bunch of our tests are
using 2ms tick times instead of 2000ms tick times, which may make
things fail on slower machines. do you think that is what you are
seeing?

Hi Mahadev,
Yes I am using that Jira for tracking the issues I noticed with the tests. In my last run, the set of tests failing with timeout changed a bit so I am digging in to see what could be going on.
Thanks!
