Columns missing after upgrade from 0.8 to 1.0.7.
------------------------------------------------

                 Key: CASSANDRA-3820
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3820
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.0.7
            Reporter: Jason Harvey


After an upgrade, one of our CFs had a lot of rows with missing columns. I've been able to
reproduce in test conditions. Working on getting the tables to DataStax(data is private).

A few notes:

* The rows with missing data were fully restored after scrubbing the sstables.
* The row which I reproduced on happened to be split across multiple sstables.
* When I copied the first sstable I found the row on, I was able to 'list' rows from the sstable,
but any and all 'get' calls failed.
