Description

Currently many all the files created by the HBase user are just written using the default file permissions granted by hdfs. However, to ensure only the correct user/group views the files and directories, we need to be able to apply a configurable umask to either directories or files.

This ticket covers setting permissions for files written to dfs, as opposed to things like pid and log files.

The impetus for this was to allow the web-user to view the directory structure of hbase, but not to actually see any of the actual data hbase is storing.
