I would try nodetool resetlocalschema.

Hi list
We have a 5-node Cassandra cluster with a single 1.0.9 installation
and four 1.0.6 installations.
We have tried installing 1.1.4 on one of the 1.0.6 nodes (following
the instructions on http://www.datastax.com/docs/1.1/install/upgrading).
After bringing up 1.1.4 there are no errors in the log, but the
cluster now suffers from schema disagreement
[default@unknown] describe cluster;
Cluster Information:
Snitch: org.apache.cassandra.locator.SimpleSnitch
Partitioner: org.apache.cassandra.dht.RandomPartitioner
Schema versions:
59adb24e-f3cd-3e02-97f0-5b395827453f: [10.10.29.67] <-The new 1.1.4 node
943fc0a0-f678-11e1-0000-339cf8a6c1bf: [10.10.87.228, 10.10.153.45,
10.10.145.90, 10.38.127.80] <- nodes in the old cluster
The recipe for recovering from schema disagreement
(http://wiki.apache.org/cassandra/FAQ#schema_disagreement) doesn't
cover the new directory layout. The system/Schema directory is empty
save for a snapshots subdirectory. system/schema_columnfamilies and
system/schema_keyspaces contain some files. As described in datastax's
description, we tried running nodetool upgradesstables. When this had
done, describe schema in the cli showed a schema definition which
seemed correct, but was indeed different from the schema on the other
nodes in the cluster.
Any clues on how we should proceed?
Thanks,
/Martin Koch
