map/reduce clients should not access the system dir directly
------------------------------------------------------------
Key: HADOOP-3626
URL: https://issues.apache.org/jira/browse/HADOOP-3626
Project: Hadoop Core
Issue Type: Improvement
Components: mapred
Reporter: Owen O'Malley
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.
