FAQ
dfs.data.dir permissions should default to 700
----------------------------------------------

Key: HDFS-1560
URL: https://issues.apache.org/jira/browse/HDFS-1560
Project: Hadoop HDFS
Issue Type: Bug
Components: data-node
Affects Versions: 0.22.0, 0.23.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor


Currently, dfs.data.dir defaults to 755 permissions, which isn't necessary for any reason, and is a security issue if not changed on a secured cluster. We should default to 700
