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

             Summary: zero-copy reads are incorrectly disabled on file offsets above 2GB
                 Key: HDFS-6097
                 URL: https://issues.apache.org/jira/browse/HDFS-6097
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.4.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


Zero-copy reads are incorrectly disabled on file offsets above 2GB due to some code that is supposed to disable zero-copy reads on offsets in block files greater than 2GB (because MappedByteBuffer segments are limited to that size).
