and Hortonworks Ranger integration
When Sentry or Ranger are on a Hadoop cluster that has the impersonation plug-in enabled. In this case, Datameer acts as a DFS client and respects Sentry permissionstheir (Sentry or Ranger) permissions.
The Datameer private folder in HDFS should be owned by datameer:<dasuser>, which is the group that is specified for impersonation, including its core directories. To ensure this ownership, run secure_hdfs_tool.sh.
If you want Datameer users to access resources that are controlled by Sentry, then proper privileges need to be granted from Sentry.
Datameer doesn't have any Sentry-specific integration
