回答1:
This error happens when there was a schema change, which didn't get propagated to all the nodes in Cassandra.
Run the command
nodetool describecluster
The output should contain a section called
Schema versions: 65e78f0e-e81e-30d8-a631-a65dff93bf82: [127.0.0.1]
In case of this schema disagreement, there will be more than one schema version each associated with a separate set of nodes. Restart the Cassandra nodes which are in disagreement (showing different schema versions) one by one until everyone agrees to a specific schema version.
