> val t = CollectionDataSets.get3TupleDataSet(env).as('a, 'b, 'c)
>       .groupBy('a)
>       .select('a, 'b.avg as 'value)
>       .filter('a === 1)
> {noformat}
> For this query, filter is expected to be pushed down before the aggregate by FilterAggregateTransposeRule, currently the optimzied logical plan is not what we desired.
