             Summary: Extend nodetool verify with functionality to detect partitions with duplicate keys
                 Key: CASSANDRA-17789
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17789
             Project: Cassandra
          Issue Type: New Feature
          Components: Tool/nodetool
            Reporter: Josh McKenzie
            Assignee: Josh McKenzie


We've seen instances where, during upgrades across major versions and in mixed version clusters, we end up with data in a table that has duplication of primary keys. This is obviously an illegal state and being able to quickly scan for this and log partition keys for which we're seeing this state has proven quite useful.

It's a fairly small change to verify/scrub to integrate this extra functionality.
