Answer / ankit gosain

Hi,

This problem can be solved by creating a job with following
stages:

File2 File2
| |
| |
| |
File1-----Funnel----Aggregator----Join----Filter---Tgt_File
|
|
|
File1

1. Funnel both the files (Now you have Unique & Duplicates
records).
2. Aggregate on the basis of any i/p column and mention the
calculation type = Count Rows (say o/p column row_count).
3. Join the aggregated o/p with the i/p file1,2 one the
basis of key & mention the join type = Inner Join.
4. In filter stage, mention the where clause as row_count>1.

If you have further doubt or query, catch me on

Ankit :)
