Thanks Hairong.

The updated patch disables the test Hairong mentioned with a very explicit 
comment that it is a temporary change and it has the original patch Dhruba 
attached.

> This is a temporary work around issues discussed in HADOOP-4663. 
> The proposal is to remove all the files under tmp directory, thus bringing 
> the behavior back to 0.17. The main cost is that sync() will not be 
> supported. This is incompatible with 0.18.x, but not with 0.17 because of 
> this reason.
