> The getDU method should not include the size of the directory. The Java
> interface says that the value is undefined and in Linux/Sun it gets the 4096
> for the inode. Clearly this isn't useful.
> It also recursively calls itself. In case the directory has a symbolic link
> forming a cycle, getDU keeps spinning in the cycle. In our case, we saw this
> in the org.apache.hadoop.mapred.JobLocalizer.downloadPrivateCacheObjects
> call. This prevented other tasks on the same node from committing, causing
> the TT to become effectively useless (because the JT thinks it already has
> enough tasks running)
