https://github.com/apache/flink/pull/2870
I've fixed all things above.
Though, I've faced some problems while moving to another test base. It uses
testing expressions directly in SELECT query, so I had to add new case in
ProjectionTranslator's expression parsing.
Also I think that we have to use BigDecimal#stripTrailingZeros in casting,
because I think we expect that BigDecimal(2.0) should be equal to
BigDecimal(2.00). It affected
AggregationsITCase#testWorkingAggregationDataTypes.
