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

             Summary: DN WebHDFS methods throw NPE if Namenode RPC address param not specified
                 Key: HDFS-3490
                 URL: https://issues.apache.org/jira/browse/HDFS-3490
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node
    Affects Versions: 2.0.0-alpha
            Reporter: Todd Lipcon
            Priority: Minor


Currently, there is no validation done on the NamenodeRpcAddressParam. If it is not passed to the datanode webhdfs methods, an NPE will be generated trying to use it. We should instead have some kind of validation on the parameter and throw a more appropriate error message when it is missing.
