Transform bag of key-value tuples to map in Apache Pig

Question

I am new to Pig and I want to convert a bag of tuples to a map with specific value in each tuple as key. Basically I want to change:

{(id1, value1),(id2, value

Answer 1

I ran into the same situation so I submitted a patch that just got accepted: https://issues.apache.org/jira/browse/PIG-4638

This means that what you wanted is a core part starting with pig 0.16.
