Having a quick look an the plan: the repartition will partition into a single partition (because you only have a single unique key) which is likely not the first partition. The stream for the first partition will only advance when `RepartitionExec` either gets an element that is hashed into it (never in your case) or when the input terminates. However I don't understand why this is an issue here, because `CoalescePartitionsExec` polls all streams/partitions in parallel. So there's indeed some bug here. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
