2. c) Aggregator Stage Properties :
Input data contains only one column "No" , In Aggregator stage, we have group the data on the "No" column and calculate the rows for each Key (
No ).
d) Filter Stage Properties :
In Filter stage, we put 2 where condition count=1 and count>1. and assigned different links to both conditions.
From filter Stage, first link (count=1) map to output file ( which contains the unique records )
and second link we map with Join stage.
e) Join Stage Properties :
In join stage, we join the both input on key column (No).
