Subject java.lang.AssertionError: Added column does not sort as the last column
Date Tue, 03 Jun 2014 18:47:50 GMT
Has anyone seen this error on Cassandra 1.2.9? We have not done any upgrades or changes to
column families since we went live in feb 2014.

 

we are getting the following error when we run the nodetool cleanup or nodetool repair on
one of our Production Nodes. 

We have 2 data ceners with 2 nodes in each data center and with replication factor 2. We only
see this error on one of the Nodes.
