Hi I'm getting the following at startup on one of the nodes on my 3 node cluster with RF=3. I have 6 keyspaces each with 10 column families that contain supercolumns that contain only counter columns.
Looking at http://www.datastax.com/dev/blog/whats-new-in-cassandra-0-8-part-2-countersI see that I am supposed to "remove all data for that column family". Does looking at the previous line for the same thread tell me which column family this is happening to ? How do I "remove the data" on that node ?
