             Summary: ksck checksum scans fail on large tables/clusters
                 Key: KUDU-2512
                 URL: https://issues.apache.org/jira/browse/KUDU-2512
             Project: Kudu
          Issue Type: Bug
          Components: ksck
            Reporter: Grant Henke


ksck checksum scans can fail when the time to run takes longer than the default ancient history mark. This happened on a cluster wide checksum scan and a table specific checksum scan.

The error message is clear, but perhaps we could improve the logic to make failure less likely on large clusters or tables with a default ancient history mark.
