> In `org.apache.spark.streaming.kinesis` there's a Java interface
> `KinesisInitialPosition` - for some reason it's not public, so can't be used.
> The reason it needs to be used is simple: it is the parent of
> `KinesisInitialPositions.Latest` and `KinesisInitialPositions.TrimHorizon`.
> Without using it, it's impossible to pass instances of `Latest` and
> `TrimHorizon` around without calling them by name.
> The workaround is to use the enum `InitialPositionInStream` instead, and a
> factory method `fromKinesisInitialPosition(..)` - but it doesn't seem like
> the correct pattern, because it belongs to Amazon Kinesis Client library and
> not Spark (it's currently the only import in my class which is outside of
> `org.apache.spark`).
> The change is trivial, so it's mainly a matter of why *not* to do it.
