Hi, all sorry to resend a email with correct title .
Found a fatal bug starting from Flink 1.6, which cause Flink Table API can not correctly extract table schema . Jira https://issues.apache.org/jira/projects/FLINK/issues/FLINK-13603?filter=allopenissues there is a change on Flink-core -> RowTypeInfo -> hashcode , this change make FlinkTypeFactory recognize schema with same type but different field name as a same TypeInfo , this cause table schema can not be parsed correctly . Is any plan to fix this ? as the reverting hashcode change may fix the problem, but I'm not sure other side affect of this change . Thanks
