Aaron T. Myers created HDFS-5408:
------------------------------------

             Summary: Optional fields in PB definitions should be optional in HTTP deserialization as well
                 Key: HDFS-5408
                 URL: https://issues.apache.org/jira/browse/HDFS-5408
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 2.2.0
            Reporter: Aaron T. Myers


As was pointed out by [~andrew.wang] in HDFS-5403, there are a few fields which are marked as optional in PB definitions but then assumed to always exist in the JSON deserialization of the WebHdfs client. We should handle the possibility that these fields will not be present in WebHdfs as well.
