liupc commented on issue #23614: [SPARK-26689][CORE]Support blacklisting bad disk directory and retry in DiskBlockManager URL: https://github.com/apache/spark/pull/23614#issuecomment-463580209 @squito I know your concern, and I think you are right, there might be some risk about the inconsistent behavior with the external shuffle service, I need to think carefully about how to solve the problem. Maybe, one solution is to call `BlockManager` to reregister with external shuffle server, and update the `executorShuffleInfo` of external shuffle service.
