Till Rohrmann commented on FLINK-2197:
--------------------------------------
I haven't found a good solution for this problem yet. Importing the function
from the batch API adds it as a dependency to the streaming API. I think that's
not what we want. We could pull {{createTypeInformation}} out into a new module
which both APIs use. But then you always would have to import this package
object and the package objects of the batch/streaming API if they contain more
implicit values.
> Scala API is not working when using batch and streaming API in the same
> program

>
> If one uses the the Scala batch and streaming API from within the same
> program and imports both corresponding package objects, then the Scala API no
> longer works because it is lacking the implicit {{TypeInformation}} values.
> The reason for this is that both package objects contain an implicit function
> {createTypeInformation}}. This creates an ambiguity which is not possible for
> the Scala compiler to resolve.
