-------------------------------

Hi [~rohithsharma]
On a second thought, could we move {{refreshAll}} in 
{{AdminService#transitionToStandby/Active}} ahead of 
{{rm.transitionToStandby/Active}}
{code}
    try {
      // call all refresh*s for active RM to get the updated configurations.
      refreshAll();
      rm.transitionToActive();
      RMAuditLogger.logSuccess(user.getShortUserName(),
          "transitionToActive", "RMHAProtocolService");
    } catch (Exception e) {
      RMAuditLogger.logFailure(user.getShortUserName(), "transitionToActive",
          "", "RMHAProtocolService",
          "Exception transitioning to active");
      throw new ServiceFailedException(
          "Error when transitioning to Active mode", e);
    }
{code}

Hence exception can come before invoking transition methods in ResourceManager 
class. Thoughts?
