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

             Summary: When short circuit read is disallowed, DFSClient does disable short circuit and fall back to regular reads
                 Key: HDFS-4595
                 URL: https://issues.apache.org/jira/browse/HDFS-4595
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.0.0-alpha
            Reporter: Suresh Srinivas
            Assignee: Suresh Srinivas


In 1.0, when short circuit is disallowed for a user, the DFSClient disables short circuit and falls back to the regular socket based reads over DataTransferProtocol. In release 2.0, this fallback functionality is not working.
