Hello, everybody! I have a bunch of records. Each record has key, and two fields A,B - R(k, A,B) I want to build two inverted indexes, one per each field. As output I expect two files IndexA =(A1- [k1,k2,k3..]),(A2 -[k1,k2,k4...]) ... IndexB =(B1- [k1,k2,k3..]),(B2-[k1,k2,k4...]) ...
Hadoop mapper allows to write out only one key value pair. Of cause, I can run it twice, but I don't want to read the same record twice. What is the best way to handle this situation?
