----------------------------------

             Summary: Improve TableSchema ValidationException message.
                 Key: FLINK-7572
                 URL: https://issues.apache.org/jira/browse/FLINK-7572
             Project: Flink
          Issue Type: Improvement
            Reporter: sunjincheng
            Assignee: sunjincheng


When sql is very complicated(e.g.: more than 100+ tables), the following exception information
is very confusing:
{code}
org.apache.flink.table.api.TableException: Table column names must be unique. at org.apache.flink.table.api.TableSchema.<init>(TableSchema.scala:36)
{code}
