Owen O'Malley resolved HADOOP-528.

    Resolution: Cannot Reproduce
      Assignee:     (was: Owen O'Malley)

I haven't seen this recently and I suspect it was the race condition in creating the directories
that we used to have with mkdirs calling exists and then mkdir.

> On some nodes hadoop distcp fails with folowing error. The property dfs.client.buffer.dir
is defined in hadoop-site.xml and the corresponding directory is also created on the node
by framework. Same configuration works on all other nodes. 
> It could be a timing issue where someone is trying to read the dir before its created
on local disk, I am not sure of the cause. 
> java.io.IOException: No valid local directories in property: dfs.client.buffer.dir at
