[GitHub] [spark] zsxwing commented on pull request #30812: [SPARK-33814][SS] Provide preferred locations for stateful operations without reported state store locations

   IMO, this looks a hacky approach to workaround a Spark task scheduler issue. Have we tried to improve Spark's task scheduler which will be a general improvement for all cases that miss preferred locations? For example, reading files from a cloud storage such as S3 has the same issue. Right?
