                 URL: https://issues.apache.org/jira/browse/FLINK-15479
             Project: Flink

            Reporter: hailong wang
             Fix For: 1.10.0


JDBCTableSource support project push down, when the final fieldNames is inconsistent with that in tableSchema, the source's explanation will be wrong. So we should override explainSource method for it.
