[jira] Created: (MAPREDUCE-808) Buffer objects incorrectly serialized to typed bytes

Buffer objects incorrectly serialized to typed bytes
----------------------------------------------------

                 Key: MAPREDUCE-808
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-808
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/streaming
    Affects Versions: 0.21.0
            Reporter: Klaas Bosteels


{{TypedBytesOutput.write()}} should do something like

{code}
Buffer buf = (Buffer) obj;
writeBytes(buf.get(), 0, bug.getCount());
{code}

instead of

{code}
writeBytes(((Buffer) obj).get());
{code}

since the bytes returned by {{Buffer.get()}} are "only valid between 0 and getCount() - 1".
