--------------------------------
Summary: Design a scan to detect KUDU-2233 corruption in a replica
Key: KUDU-2793
URL: https://issues.apache.org/jira/browse/KUDU-2793
Project: Kudu
Issue Type: Task
Components: tablet
Affects Versions: 1.8.0
Reporter: Mike Percy
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.
