Rohini Palaniswamy commented on PIG-4400:
-----------------------------------------
PIVOT is a new operator and should go into the main docs and not perf section.
What does HII stand for? We should come up with some name which is more user
understandable. Also from the doc example, I am not very clear what the value
for PIVOT actually is. Also it would be better if we can explain in few lines
what is done instead of having to read a full paper. More simple (for dummies)
and detail the documentation, less time spent explaining to users how it works.
Can you give me time till this weekend? I would like to finish reading the
paper and go back and review PIG-4066 and see how it is done and also how it
can be applied for Tez and Spark mode. I feel that we need to better integrate
this into Pig and make it a first class citizen instead of having it in perf
section.
