             Summary: Add retry logic for DB Setup during Ranger upgrade step (to handle upgrade with Ranger HA)
                 Key: AMBARI-15127
                 URL: https://issues.apache.org/jira/browse/AMBARI-15127
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.1
            Reporter: Gautam Borad
            Assignee: Gautam Borad
             Fix For: 2.2.2


*Problem Statement*
Need to apply multiple retries for Ranger DB setup calls to handle concurrent calls to one DB from 2 different hosts where Ranger Admin is installed. 

This scenario is needed to handle upgrades of HDP  in a case when Ranger HA is enabled.
