-------------------------------------------------
Summary: make user's mapred .staging area permissions configurable
Key: MAPREDUCE-4555
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4555
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: client, job submission
Affects Versions: 1.0.3
Reporter: Alexander Alten-Lorenz
The directories are created in JobTracker and LocalRunner, but they are
currently forced to be 0700. There is even a segment of the source code that
will check the permissions are 0700, and if not it will change the permissions
to match 0700. For monitoring purposes the permissions should be configurable.
Please note:
1. We can make the hard-coded 700 configurable at clients (its the client who
creates it) but there's two issues here:
1.1. It violates security principals (as its client sided and overridable)
1.2. It can't be consistent, since some user may ignore configs provided to
them and create it with 0700.
