URL: https://github.com/apache/spark/pull/29321


   This is a partial backport of https://github.com/apache/spark/pull/29307
   
   Most of the changes are not needed because https://github.com/cloud-fan/spark/commit/69f9ee18b66991f8d6989fa20f93cd7343be28a9#diff-3ad09c07c2a3bc71e3c90d3307bb9611 is in master only.
   
   This PR only backports the safeguard in `ShuffleExchangeExec.canChangeNumPartitions`
