Plamen Jeliazkov updated MAPREDUCE-2786:
----------------------------------------
Attachment: MAPREDUCE-2786.patch
This is my work done so far. I'd like to move the codec into the mapper
constructors but I have not been able to do it successfully because the
CompressionOutputStream relies on the OutputStream within each mapper.
> TestDFSIO should also test compression reading/writing from command-line.

> After running into trouble dealing with the config files I thought it might
> be easier to simply alter the code of TestDFSIO to accept any compression
> codec and allow testing for compression by a command line argument instead of
> having to change the config file everytime. Something like "-compression"
> would do.
