does this significantly increase the test runtime? |

I didn't see significant difference. It is about 450~500 milliseconds. |

There was a problem hiding this comment.
The default interval is 15millis, IIUC. It is more possibly that the range stage finishes in the interval. So reduce it to 1millis.

## What changes were proposed in this pull request? It is reported that the test `Cancelling stage in a query with Range` in `DataFrameRangeSuite` fails a few times in unrelated PRs. I personally also saw it too in my PR. This test is not very flaky actually but only fails occasionally. Based on how the test works, I guess that is because `range` finishes before the listener calls `cancelStage`. I increase the range number from `1000000000L` to `100000000000L` and count the range in one partition. I also reduce the `interval` of checking stage id. Hopefully it can make the test not flaky anymore. ## How was this patch tested? The modified tests. Author: Liang-Chi Hsieh <viirya@gmail.com> Closes #20431 from viirya/SPARK-23222. (cherry picked from commit 84bcf9d) Signed-off-by: Wenchen Fan <wenchen@databricks.com>
