I would suggest to change the error message in all places to something like
"Operator <op> does not support configuring custom resources specs".
> Support to set resource for operator in DataStream and DataSet

>
> This is part of the fine-grained resource configuration.
> For *DataStream*, the *setResource* API will be setted onto
> *SingleOutputStreamOperator* similar with other existing properties like
> parallelism, name, etc.
> For *DataSet*, the *setResource* API will be setted onto *Operator* in the
> similar way.
> There are two parameters described with minimum *ResourceSpec* and maximum
> *ResourceSpec* separately in the API for considering resource resize in
> future improvements.
