Edward Capriolo commented on HIVE-1608:
---------------------------------------
It is not much. SequenceFile + none (codec) only ads some block information
around text. I still thing sequence by default is a good idea. It makes it
easier to add compression later without sacrificing split- ablility.
> use sequencefile as the default for storing intermediate results

> The only argument for having a text file for storing intermediate results
> seems to be better debuggability.
> But, tailing a sequence file is possible, and it should be more space
> efficient
