Keeping around temp datasets

[Alexander Alexandrov]

Hi there,

I have to implement some generic fallback strategy on top of a more
abstract DSL in order to keep datasets in a temp space (e.g. Tachyon). My
implementation is based on the 0.8 release. At the moment I am undecided
between three options:

   - BinaryInputFormat / BinaryOutputFormat
   - AvroInputFormat / AvroOutputformat
   - Something better (?)

What are your suggestions?
