2585 try {
2586 rm.getRMContext().getRMAdminService().refreshQueues();
2587 } catch (IOException | YarnException e) {
2588 LOG.error("Exception thrown when formatting configuration.", e);
2589 mutableConfigurationProvider.revertFromOldConfig(conf);
2590 throw e;
2591 }
2592 rm.getRMContext().getRMAdminService().refreshQueues(); {code}
1. Here refreshQueues is repeated again. Pls check this. Thanks [~Prabhu Joseph]
2. Rename revertFromOldConfig ==> revertToOldConfig
