Alan Gates commented on PIG-162:
--------------------------------
Two questions on changes1.patch:
# In order to address the issue that we need to make the index of the tuple
part of the sort key in cogroup, you've changed your map and reduce
implementations to always use Tuple as a key type. This makes the code easier.
Are there performance implications?
# Why all the changes of res.result = new Boolean(true) to res.result = true?
res.result is an object so that object creation is still getting done.
> Rework mapreduce submission and monitoring
