Major Description
When service instance is created in Ranger Admin - for example a Hive instance named hivedev, the name of the default policies created are of format: serviceName-count-timestamp; like hivedev-1-20160510202411 and hivedev-2-20160510202411
Given that these policies are created for all resources (*), a better name format would be: all - <resource1>; like all - database,table,column and all - database,udf.
Please review and update the naming of the default policies.
