             Summary: Users in policy got changed after upgrade
                 Key: RANGER-748
                 URL: https://issues.apache.org/jira/browse/RANGER-748
             Project: Ranger
          Issue Type: Bug
          Components: admin, usersync
    Affects Versions: 0.5.1
            Reporter: Gautam Borad
            Assignee: Gautam Borad
             Fix For: 0.5.1, 0.6.0


*Issue*
After upgrading ranger from older version to latest : Users in x_user and x_portal_user tables are not in sync and due to this policies populates wrong users after upgrade and service check of plugin components fails. 


*Root cause*
As part of [commit | https://github.com/apache/incubator-ranger/commit/7c185e1f5a8881fd7a7ad0d60abd756b3cd416ec] -   RangerPolicyRetriever.java [Line No: 253]. Code is to read username using userId. In this function, userId being passed is of x_user table but code written is to read it from x_portal_user.

So when IDs in x_user and x_portal_user are not in sync, this code will return wrong username, and that's why username in policies will be changed with some other username.
