Alright, so what went wrong here is that for CollectLeft joins, the left ExecutionPlan gets executed *for every input partition*. This was not caught by the tests 2 weeks ago, because most plans can have a partition executed multiple times - but repartition can not. I suspect there is no case where a CollectLeft join is used and a RepartitionExec is under the build side. -- This is an automated message from the Apache Git Service.
