Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.1
Reporter: Gautam Borad
Assignee: Gautam Borad
Fix For: 2.2.2

Need to apply multiple retries for Ranger DB setup calls to handle concurrent

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