Flaky streaming tests

Hi all,

The InputStreamsSuite seems to have some serious flakiness issues -- I've
seen the file input stream fail many times and now I'm seeing some actor
input stream test failures (
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/13846/consoleFull)
on what I think is an unrelated change.  Does anyone know anything about
these?  Should we just remove some of these tests since they seem to be
constantly failing?

-Kay

I agree these should be disabled right away, and the JIRA can be used to
track fixing / turning them back on.

There is a JIRA for one of the flakey tests here:
https://issues.apache.org/jira/browse/SPARK-1409

TD - do you know what is going on here?

I looked into this ab it and at least a few of these that use
Thread.sleep() and assume the sleep will be exact, which is wrong. We
should disable all the tests that do and probably they should be re-written
to virtualize time.

I met this issue when Jenkins seems to be very busy....
