When I log the calls of the combiner function and print the number of
elements iterated over, it is all 1 during the spill-writing phase and the
combiner is called very often. Is this normal behavior? According to what
mentioned earlier, I would expect the combiner to combine all records with
the same key that are in the in-memory buffer before the spill and it
should be at least a few per spill in my case. This is confusing...
