> 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
> Assignee: Ufuk Celebi
> 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.
