> Currently for event-time window(group/over), When contain `Timestamp` type field in `SELECT Clause`, And toDataStream[T], `T` not a `Row` Type, Such `PojoType`, will throw a exception. In this JIRA. will fix this bug. For example:
> Group Window on SQL:
> {code}
> SELECT name, max(num) as myMax, TUMBLE_START(rowtime, INTERVAL '5' SECOND) as winStart,TUMBLE_END(rowtime, INTERVAL '5' SECOND) as winEnd FROM T1 GROUP BY name, TUMBLE(rowtime, INTERVAL '5' SECOND)
> {code}
> Throw Exception:
> {code}
> org.apache.flink.table.api.TableException: The field types of physical and logical row types do not match.This is a bug and should not happen. Please file an issue.
> at org.apache.flink.table.api.TableException$.apply(exceptions.scala:53)
> at org.apache.flink.table.api.TableEnvironment.generateRowConverterFunction(TableEnvironment.scala:721)
> at org.apache.flink.table.api.StreamTableEnvironment.getConversionMapper(StreamTableEnvironment.scala:247)
> at org.apache.flink.table.api.StreamTableEnvironment.translate(StreamTableEnvironment.scala:647)
> {code}
> In fact, when we solve this exception,subsequent other exceptions will be thrown. The real reason is {{TableEnvironment#generateRowConverterFunction}} method bug. So in this JIRA. will fix it.
