Hi Shail, Below mentioned steps are mentioned in Ranger Guide to enable Ranger plugin In Hadoop HA cluster
To enable Ranger in the HDFS HA environment, an HDFS plugin must be set up in each NameNode, and then pointed to the same HDFS repository set up in the Security Manager. Any policies created within that HDFS repository are automatically synchronized to the primary and secondary NameNodes through the installed Apache Ranger plugin. That way, if the primary NameNode fails, the secondary namenode takes over and the Ranger plugin at that NameNode begins to enforce the same policies for access control. When creating the repository, you must include the fs.default.name for the primary NameNode. If the primary NameNode fails during policy creation, you can then temporarily use the fs.default.name of the secondary NameNode in the repository details to enable directory lookup for policy creation.
