Github user JoshRosen commented on the pull request: https://github.com/apache/spark/pull/4008#issuecomment-69658255 Oh, and to provide a little more context, the reason that we're able to cancel most tasks even though we don't perform thread interrupts is that we have an [InterruptibleIterator](https://github.com/uncleGen/spark/blob/master-clean-150112/core/src/main/scala/org/apache/spark/InterruptibleIterator.scala) class that causes canceled tasks to throw exceptions when they try to consume their next element of input. That doesn't seem to take effect here, though, because our receiver task doesn't consume any input.
