> Remove ClassTag in Scala DataSet API
> ------------------------------------
>
> Key: FLINK-7691
> URL: https://issues.apache.org/jira/browse/FLINK-7691
> Project: Flink
> Issue Type: Sub-task
> Components: API / DataSet
> Reporter: Timo Walther
> Priority: Major
> Fix For: 2.0.0
>
>
> In the DataStream API a {{ClassTag}} is not required, which allows to pass
> {{TypeInformation}} manually if required. In the DataSet API most methods
> look like:
> {code}
> // DataSet API
> def fromElements[T: ClassTag : TypeInformation](data: T*): DataSet[T]
> // DataStream API
> def fromElements[T: TypeInformation](data: T*): DataStream[T]
> {code}
> I would propose to remove the ClassTag, if possible. This would make it
> easier e.g. to supply TypeInformation for the {{Row}} type. Or is there an
> easier way in Scala that I don't know?
