Hi all： 建表语句 create table `source_table`( `SeqNo` varchar, `Type` varchar, `Table` varchar, `ServerId` varchar, `Database` varchar, `OldData` varchar, `GTID` varchar, `Offset` varchar, `event_ts` as to_timestamp(from_unixtime(Data.`FuiUpdateTime`),'yyyy-MM-ddHH:mm:ss'), WATERMARK FOR event_ts AS event_ts - interval '60' second ) with(…)
查询语句 insert into sinkTable from Select * from source_table； 报错信息： java.lang.ClassCastException: java.sql.Timestamp cannot be cast to java.lang.Long at org.apache.flink.api.common.typeutils.base.LongSerializer.copy(LongSerializer.java:32) at org.apache.flink.api.java.typeutils.runtime.RowSerializer.copy(RowSerializer.java:93) at org.apache.flink.api.java.typeutils.runtime.RowSerializer.copy(RowSerializer.java:44) at org.apache.flink.api.java.typeutils.runtime.TupleSerializer.copy(TupleSerializer.java:115) at org.apache.flink.api.java.typeutils.runtime.TupleSerializer.copy(TupleSerializer.java:37) at org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.pushToOperator(OperatorChain.java:639) at org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:616) at org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:596) at org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:730) at org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:708) at SinkConversion$51.processElement(Unknown Source) …… 最后查看代码，发现对于rowtime,在BaseRowTypeInfo下会是使用SqlTimestampSerializer，而在RowTypeInfo会使用LongSerializer,上下游使用serializer不一样，上游使用SqlTimestampSerializer下游使用LongSerializer就会报错。 请问这个问题可以避免吗？
