>
> FLINK-5801 shows a very hard to debug issue when querying state from the
> Scala API that can result in serializer mismatches between the client and the
> job.
> We should mention that the type serializers should be created via the Scala
> macros.

> import org.apache.flink.streaming.api.scala._
> ...
> val keySerializer = createTypeInformation[Long].createSerializer(new
> ExecutionConfig)
> {code}
