Unfortunately, the Enumerate UDF from DataFu would not work in this case. The UDF works on Bags and in this case, we want to enumerate a relation. Implementing RANK is a very tricky thing to do correctly. I'm not even sure if it's doable just by using Pig operators, UDFs or macros. Best option is probably to request a Pig upgrade.
