> If a replica is corrupted due to generation stamp mismatch, the corresponding datanode stores a wrong generation stamp while `invalidateCorruptReplicas()` will send right generation stamp to the datanode. Therefore, the check on datanode can not pass successfully as discussion in [https://github.com/apache/hadoop/pull/5643.] resulting in the corrupted replica unable to be successfully deleted.
