Description

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.

Traceback (most recent call last):
