Chris Douglas commented on HADOOP-5869:
---------------------------------------
My original comments were based on the results of a git-bisect from the last
successful Hudson revision to HEAD (w/ 10 min timeout), identifying HADOOP-5792
as the first point where TestQueueCapacities started failing; dropping
HADOOP-5792 from the tree identified HADOOP-4981 as a point where a failure
resurfaced. I confirmed manually within the bisect branch before reopening the
prenominate issues, but fresh subversion checkouts of the relevant revisions
_do not_ exhibit the behavior I reported previously. I must be mistaken. Thanks
for doing the real work on this, Sreekanth.
After applying the patch to a fresh checkout, the test still times out on my
machine...
