Subject [jira] [Created] (PHOENIX-5070) NPE when upgrading Phoenix 4.13.0 to Phoenix 4.14.1 with hbase-1.x branch
Date Fri, 14 Dec 2018 09:33:00 GMT
Monani Mihir created PHOENIX-5070:
-------------------------------------

             Summary: NPE when upgrading Phoenix 4.13.0 to Phoenix 4.14.1 with hbase-1.x branch
                 Key: PHOENIX-5070
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5070
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.14.1, 4.14.0
            Reporter: Monani Mihir
            Assignee: Monani Mihir


PhoenixAccessController populates accessControllers during calls like loadTable before it
checks if current user has all required permission for given Hbase table and schema. 

With Phoenix-4661 , We somehow removed this for only preGetTable func call. Because of this
when we upgrade Phoenix from 4.13.0 to 4.14.1 , we get NPE for accessControllers in PhoenixAccessController#getUserPermissions. 
Here is exception stack trace :-
