Rather than apply a patch that effectively reverts HADOOP-803, it
would be better to revert the patch using svn and then apply the
neccessary (one line) patch to re-introduce the change needed by the
overlapping HADOOP-855 patch. The svn command that I've applied and
tested is:
svn merge -r 496845:496844 .
(where . is my trunk directory)
I will also attach the one line diff that was necessary to apply
after the above merge command.

Yes, the test started failing 20% of the time since HADOOP-803 was

-------------------------------------
Thanks Nigel. Was the test failing 20% of the time before any of
these patches? Was it occationally failing before HADOOP-803 was
checked in?
