Hudson commented on HDFS-3577: ------------------------------ Integrated in Hadoop-Hdfs-trunk-Commit #2560 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk-Commit/2560/]) HDFS-3577. In DatanodeWebHdfsMethods, use MessageBodyWriter instead of StreamingOutput, otherwise, it will fail to transfer large files.
