>>> So this is a Scan or a Get?
I am using Scan with a filter. It would check for rows which satisfy the
condition, say, B>> What's D? Or you meant C? And to find all those values, is it another
scan/get on a third table that gives you your D that you insert in a fourth
table?
I meant C :). Yes, I

Hello JD,
Thank you for the response.
>>> Are the Gets done on the same row that is mapped? Or on the same table?
Or another table?
By row that is mapped, does it mean the row that is given to the map()
method as a pair? Then no, the data from this row is used to construct
a filter which is
I'm still confused by 2 things:
- Are the Gets done on the same row that is mapped? Or on the same
table? Or another table?
- Can you give a real example of what you are trying to achieve?
(with fake data)
Thx

I will try & explain better this time.
The overall objective -- from the complete dataset, obtain a subset of it to
work on. Now this subset would be obtained by making use of the 2-3
conditions (filters). The setting up of one filter depends on t

Hello all,
In the data, I have to check for multiple conditions and then work
with the data that satisfies all the conditions. I am doing this as an MR
job with no reduce and the conditions are translated to a set of filters.
Among the multiple conditions (2 or 3 max), data that satisfies on
