    Description

      We should design a scan to detect corruption in a replica as a result of KUDU-2233. This may simply be a checksum scan, which we already support, but that has not been verified.

      Today, when compaction is triggered in a KUDU-2233 corrupted replica, the tablet server will crash with a CHECK error. Ideally, when this detection scan notices such a corruption, it would cause the corrupt local replica to enter a FAILED tablet state. However, causing a crash might also be acceptable in controlled scenarios.
