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

             Summary: Some usage of GetConf tool not compatible with federation
                 Key: HDFS-4202
                 URL: https://issues.apache.org/jira/browse/HDFS-4202
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: federation, scripts
    Affects Versions: 2.0.2-alpha, 3.0.0
            Reporter: Todd Lipcon
            Priority: Minor


In the start/stop scripts, we use the "getconf" tool to look up certain config keys to discover hosts we need to start/stop daemons on. However, some of these configs are optionally suffixed by a nameservice or nameservice.namenode identifier. In these cases, the start/stop scripts wouldn't correctly see the configs, and therefore would fail to start all the necessary daemons for the federated cluster.
