Apache Ranger™ is a framework to enable, monitor and manage comprehensive data security across the Hadoop platform. Apache Ranger has supported Ozone authentication since version 2.0. However, due to some bugs in 2.0, Apache Ranger 2.1 and later versions are recommended.
To use Apache Ranger, you must have Apache Ranger installed in your Hadoop Cluster. For installation instructions of Apache Ranger, Please take a look at the Apache Ranger website.
If you have a working Apache Ranger installation that is aware of Ozone, then configuring Ozone to work with Apache Ranger is trivial. You have to enable the ACLs support and set the acl authorizer class inside Ozone to be Ranger authorizer. Please add the following properties to the ozone-site.xml.
| Property | Value |
|---|---|
| ozone.acl.enabled | true |
| ozone.acl.authorizer.class | org.apache.ranger.authorization.ozone.authorizer.RangerOzoneAuthorizer |
To use the RangerOzoneAuthorizer, you also need to add the following environment variables to ozone-env.sh:
export OZONE_CLASSPATH="${OZONE_HOME}/share/ozone/lib/libext/*"
The Ranger permissions corresponding to the Ozone operations are as follows:
| operation&permission | Volume permission | Bucket permission | Key permission |
|---|---|---|---|
| Create volume | CREATE | ||
| List volume | LIST | ||
| Get volume Info | READ | ||
| Delete volume | DELETE | ||
| Create bucket | READ | CREATE | |
| List bucket | LIST, READ | ||
| Get bucket info | READ | READ | |
| Delete bucket | READ | DELETE | |
| List key | READ | LIST, READ | |
| Write key | READ | READ | CREATE, WRITE |
| Read key | READ | READ | READ |
