Answered 2020-Sep-06 at 02:15In my opinion the best way is to structure the data first and render it later, so you dont have to mess around with closing tags etc. You could use a for loop and iterate over every 2 item to create the table.

is a black-box for the Table & SQL API runtime as the number of fields and their datatype is undefined. I would recommend to use a Avro-generated class which extends SpecificRecord

for one of the reducer keys. You're not outputting any AUTOMOBILE record in the mapper because you insist that the balance exceeds 8000 and the nation be in (1, 15). EDIT: I see now that you're pulling in a lot more data than the 7 sample records you posted.
This may also be a problem, once you get your count thing figured out:
