Konstantin Boudnik commented on HDFS-1829:
------------------------------------------
I think it makes sense to have a new private method instead of copying pretty
much the same code 3 times. Surely the iterators in while loops are different
methods but I think you can parametrized it via Callable.

> In three locations in the code, TestNodeCount waits forever on a condition.
> Failures result in Hudson/Jenkins "Timeout occurred" error message with no
> information about where or why. Need to replace with TimeoutExceptions that
> throw a stack trace and useful info about the failure mode.
> Also investigate possible cause of failure.
