-----------------------------------------
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.
