For authentication you have to use Kerberos. Apache Knox also provides AD/LDAP authentication and security for components supporting JDBC/ODBC and REST APIs. Depending upon which Hadoop components you are using, you can also use their native features. You should also look into Apache Sentry. It is also open source providing security for various Hadoop components. >2. Moreover is Solr is the prerequisite of Apache ranger? While it is not mandatory, it is highly recommended. Ranger can send audit records to multiple destinations simultaneously. If you send audits to Solr, then you can do real-time query using Ranger Admin UI. You should also send to HDFS for long time archival and doing offline analytics. >3.

All features of Apache Ranger, including it's policy administration are 100% open source and released under Apache license. If you are aware of any specific components or libraries you are concerned of, then please let us know. We should be able to clarify or rectify it.
