Subject [jira] [Created] (HDFS-6214) Webhdfs has poor throughput for files >2GB
Date Wed, 09 Apr 2014 15:00:29 GMT
Daryn Sharp created HDFS-6214:
---------------------------------

             Summary: Webhdfs has poor throughput for files >2GB
                 Key: HDFS-6214
                 URL: https://issues.apache.org/jira/browse/HDFS-6214
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 2.0.0-alpha, 3.0.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


For the DN's open call, jetty returns a Content-Length header for files <2GB, and uses
chunking for files >2GB.  A "bug" in jetty's buffer handling results in a ~8X reduction
in throughput.
