Subject [jira] Created: (CASSANDRA-2309) Scrub resulting in "Keys must be written in ascending order" exception
Date Thu, 10 Mar 2011 19:12:59 GMT
Scrub resulting in "Keys must be written in ascending order" exception
----------------------------------------------------------------------

                 Key: CASSANDRA-2309
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2309
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.7.3
            Reporter: Jason Harvey


Getting the following when I try to scrub. The SSTable causing it is over a gig. Trying to
repro on smaller tables so I have something to upload.
