As we know, the priority order of the configuration is : CommandLine > user stormconf > storm.yaml > defaults.yaml

Must be json-serializable"); } stormConf = new HashMap(stormConf); stormConf.putAll(Utils.readCommandLineOpts()); Map conf = Utils.readStormConfig(); conf.putAll(stormConf); stormConf.putAll(prepareZookeeperAuthentication(conf));readStormConfig(); conf.putAll(stormConf); It seems stormConf load the configuration from user stormConf, then commandLine, after that, defaults.yaml and storm.yaml. Isn’t the yaml files will overwrite the configuration in user stormConf and commandLine? Thanks.
