Subject [jira] [Updated] (FLINK-5264) Improve error message when assigning uid to intermediate operator.
Date Mon, 05 Dec 2016 14:46:58 GMT

Ufuk Celebi updated FLINK-5264:
-------------------------------
    Description: 
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.

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.
