Scott Carey commented on PIG-794:
---------------------------------
When is InternalMap used? My patch was designed to only work for Map input and
Reduce output, not intermediate serialization, and I assumed that InternalMap
wasn't used there.
We can always serialize a map as an array of (Key, Value) tuples, so that isn't
a problem other than being a little bit more difficult to write and test.

> We would like to use Avro serialization in Pig to pass data between MR jobs
> instead of the current BinStorage. Attached is an implementation of
