Question on IdentityTableReducer
Hi,
I want my Reducer to act as IdentityTableReducer based on a certain condition.
Can you please let me know if there is a neat way to achieve this instead of populating the Put objects explicitly in the reduce method after checking the condition.
Regards,
Shobha M

I want to loop through the records and if a certain condition (like field mismatch) between two records is found, I need to save the all the values to an output table.

Shobha M

Tell us more about this 'condition'?
Maybe you can do something custom in the TaskRunner that runs the reduce taasks.
