[jira] [Created] (HDFS-5403) WebHdfs client cannot communicate with older WebHdfs servers post HDFS-5306

Aaron T. Myers created HDFS-5403:
------------------------------------

             Summary: WebHdfs client cannot communicate with older WebHdfs servers post HDFS-5306
                 Key: HDFS-5403
                 URL: https://issues.apache.org/jira/browse/HDFS-5403
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 2.2.0
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers


HDFS-5306 introduced the field infoSecurePort to the DatanodeIDProto PB definition and made it optional for compatibility purposes. However, we don't correctly the handle the case when this field is not present when deserializing the response from a WebHdfs request. This results in an NPE at the client when this occurs.
