[HOD] HOD opens up directory permissions more than required
-----------------------------------------------------------
Key: HADOOP-4782
URL: https://issues.apache.org/jira/browse/HADOOP-4782
Project: Hadoop Core
Issue Type: Bug
Components: contrib/hod
Affects Versions: 0.20.0
Reporter: Hemanth Yamijala
Priority: Blocker
Fix For: 0.20.0
In HADOOP-4705, we fixed hod to grant read access to all directories and files
that HOD creates, and also set the umask such that files created by Hadoop also
get read permissions to world. In shared clusters, this is opening up too much
to the users. This issue is for resetting the permissions to be as constrained
as possible, while still addressing the requirement raised in HADOOP-4705.
