These ranger-admin sessions are created by "download policy actions" performed by RangerPlugins in NameNode, HiveServer process. They are authenticating to ranger-admin process using their service kerberos credentials (hdfs, hive).

@Sami Ahmad These messages are the Ranger plugins for HDFS and Hive connecting to Ranger Admin to check that they have the latest policies. If you want to stop these messages then you'll need to turn the Ranger Admin logging down to WARN, but these messages are normal. If you look at the frequency they'll occur every 30 seconds which is the default polling period for the plugins.
