> Key: HDFS-3096
> URL: https://issues.apache.org/jira/browse/HDFS-3096
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: data-node
> Affects Versions: 0.23.0, 1.0.0
> Reporter: Bikas Saha
> Assignee: Bikas Saha
>
> dfs.datanode.data.dir.perm is used by the datanode to set the permissions of
> it data directories. This is set by default to 755 which gives read
> permissions to everyone to that directory, opening up possibility of reading
> the data blocks by anyone in a secure cluster. Admins can over-ride this
> config but its sub-optimal practice for the default to be weak. IMO, the
> default should be strong and the admins can relax it if necessary.
> The fix is to change default permissions to 700.
