Description
I encountered this exception during one of the randomwriter runs. I think this situation can be improved by using org.apache.hadoop.fs.LocalDirAllocator that has been written to handle these kind of problems. I set the fix version as 0.14 but wonder whether it makes sense to have it in 0.13 itself (since the amount of code change would not be much).
