Go to one of the nodes, stop it and delete the Migrations and Schema files in the system keyspace. 

When you restart the node it will stream the migrations the other. Note that if the node is UP and accepting traffic it may log errors about missing CF's during this time.

Hi,

I try to add column families programatically and end up with 2 schema versions in the Cassandra cluster. Using Cassandra 0.7.

Is there a way to bring this back to normal (to one schema version) through the cli or through the API?
