Owen O'Malley commented on HADOOP-3626:
---------------------------------------
I'd propose something like:
{code}
~/.staging/$jobid/
{code}
The JobClient would create the job directory and the job tracker would move the
job directory into the system directory and delete it when the job is finished.
> map/reduce clients should not access the system dir directly

> Map/Reduce's use of the system directory with clients creating directories
> and files directly is very insecure. We should change the job client to
> create a staging directory in the user's home directory on the same file
> system as the system directory.
