[jira] [Created] (HDFS-6065) HDFS zero-copy reads should return empty buffer on EOF

[Colin Patrick McCabe (JIRA)]

Colin Patrick McCabe created HDFS-6065:
------------------------------------------

             Summary: HDFS zero-copy reads should return empty buffer on EOF 
                 Key: HDFS-6065
                 URL: https://issues.apache.org/jira/browse/HDFS-6065
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.4.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


It would be nice if the HDFS zero-copy reads mechanism returned an empty buffer 
on EOF.  Currently, it throws UnsupportedOperationException on EOF when using 
zero-copy reads, which seems confusing.
