Patrick Wendell commented on MAPREDUCE-3451:
--------------------------------------------
Just added a patch addressing the legitimate findbugs and javadoc warnings.
There were some findbugs warnings about concurrency that seemed like false
positives - not sure if there is a way to suppress them.
I can't re-create the core test failures locally... they seem related to port
contention issues and Kerberos issues around the hostname of the Hudson
machine. I don't see any direct relationship between these test failures and
the code in this patch. Could we at least re-run this in Hudson to make sure
that these tests are deterministically failing?
