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

             Summary: Improve error message when assigning uid to intermediate operator.
                 Key: FLINK-5264
                 URL: https://issues.apache.org/jira/browse/FLINK-5264
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.1.3
            Reporter: Kostas Kloudas
            Priority: Blocker
             Fix For: 1.2.0


Currently when trying to assign uid to an intermediate operator in a chain, the error message just says that it is not the right place, without any further information.

We could improve the message by telling explicitly to the user on which operator to assign the uid.

To take it one step further, I would also suggest to always ask the user to set a uid whenever possible, even if he did not try to set it.
