> 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.
