    Description

      In RelBuilder, eliminate duplicate aggregate calls. For example, if you call RelBuilder.aggregate with sum($1), sum($2), count($1), sum($1) then it would create an Aggregate with 3 aggregate calls (because sum($1) occurs twice), then add a Project [$1, $2, $3, $1]. The Project is necessary so that you get the number of output fields that you are expecting.
