Pradeep Agrawal updated RANGER-2484:
------------------------------------
    Description: 
Observing failure while importing permissions into ranger using ranger import 
API( /service/plugins/policies/importPoliciesFromFile?updateIfExists=true).

*Precondition:*
 * Create a ranger policy for resource "db1/table1/column1" with policy name 
policy-1 in service hivedev.

*Reproduction Steps:*
 * Import permissions for resource "db1/table1/column1" which has policy name 
policy-2 into hivedev service using import API mentioned above.

This results in below failure
{noformat}
 Validation failure: error code[3010], reason[Another policy already exists for 
matching resource: policy-name=[policy-1], service=[hivedev]], 
field[resources], subfield[null], type[semantically incorrect] 
{noformat}
This issue will be seen only when there is a policy that already exists for the 
resource with *different policy name* from the one that is being imported. If 
the policy names match, the policy is updated properly.

> Improve import API to merge the policies if resources are exactly same
