### What changes were proposed in this pull request? Use `org.apache.spark.TaskContext#addTaskCompletionListener` to clean up resources used by `RssShuffleDataIterator`. This avoids possible resource leaks. ### Why are the changes needed? Before this PR, `RssShuffleDataIterator` would only clean up used resources after all records read. When the `Task` fails or cancels, or runs some special logic such as `LocalLimit`, the resource will not be cleaned up. This creates potential resource leaks. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
