Description
Currently, the harness test can only test without state backend. If you use a DataView in the accumulator of the aggregate function, the DataView is a java object and held in heap, not replaced with StateMapView/StateListView which values are actually held in the state backend. We should improve the harness test to make it possible to test with state backend. Otherwise, issues such as FLINK-10674 could have never been found. With this harness test available, we could test the built-in aggregate functions which use the DataView more fine grained.
