dhruba borthakur commented on HADOOP-2256:
------------------------------------------
The trunk was broken for a short period of time today (because of some other
patch). HadoopQA happened to run the test for this patch during this window.
The build for this patch failed. Hence the failure in "core" and "findbugs"
tests. I have run the unit tests and they ran to completion.
> TestBlockReplacement unit test failed.

> and I think the reason is different.
