> Hello! I am a new contributor and actually contributing to open source for
> the very first time. :)
> I pulled down Hadoop today and when running the tests I encountered a failure
> with the TestUnbuffer#testUnbufferException test.
> The unbuffer code has recently gone through some changes and I believe this
> test case may have been overlooked. Using today's git commit
> (659e85e304d070f9908a96cf6a0e1cbafde6a434), and upon running the test case,
> there is an expect mock for an exception UnsupportedOperationException that
> is no longer being thrown.
> It would appear that a test like this would be valuable so my initial
> proposed patch did not remove it. Instead, I removed the conditions that were
> guarding the cast from being able to fire -- as was the previous behavior.
> Now when we encounter an object that doesn't have the UNBUFFERED
> StreamCapability, it will throw an error as it did prior to the recent
> changes.
> Please review and let me know what you think! :D
