[jira] [Created] (SPARK-36520) KinesisInitialPosition interface should be public

Noam Tamim created SPARK-36520:
----------------------------------

             Summary: KinesisInitialPosition interface should be public
                 Key: SPARK-36520
                 URL: https://issues.apache.org/jira/browse/SPARK-36520
             Project: Spark
          Issue Type: Improvement
          Components: DStreams
    Affects Versions: 3.1.2
            Reporter: Noam Tamim


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.
