> The default setting for
> hive.auto.convert.sortmerge.join.bigtable.selection.policy will choose the
> big table as the one with largest average partition size. However, this can
> result in a query failing because this policy conflicts with the big table
> candidates chosen for outer joins. This policy should just be a tie breaker
> and not have the ultimate say in the choice of tables.
