Junping Du commented on HADOOP-8820:
------------------------------------
Thanks Jing for the help here. However, I think the patch in HADOOP-8817 is the
latest code and it fix a bug on placing replicas (the first repilca's host is
not disallowed before). I did a lot of test (functional and performance) in a
real deployed cluster on that patch, but my "ant test" still meet some trouble
on my environment. Can you help to run ant test on that patch?
