Datameer Private Folder Owners and Permissions Are Out of Sync

Problem

Environmental details:  Datameer v6 or v7

When listing the HDFS path where Datameer's private folder is stored, you notice that users not associated with the Datameer service account own various folders within.  

You would like to return the folder to its proper ownership and permission to ensure Datameer runs successfully.

The above will instruct you to leverage the provided "secure_hdfs_tool" script. An example of the appropriate usage to sync the owners and permissions in the core path:
 
secure_hdfs_tool.sh -u -g <dm_group_name>
