James Thomas commented on HDFS-6865:
------------------------------------
[~stack], thanks for taking a look. So you saw no effect when native was not
available, right? And a new issue for the logging would be great. We can throw
the log message into a constructor or something so it's only printed once.
> Byte array native checksumming on client side (HDFS changes)
