      Description

      Yarn Logs fails for a running job in case of RM HA with rm2 active and rm1 is down.

      LogsCli getRMWebAppURLWithoutScheme only checks the first one from the RM list yarn.resourcemanager.ha.rm-ids.

      yarnConfig.set(YarnConfiguration.RM_HA_ID, rmIds.get(0));
      

      SchedConfCli also fails
