Project: Cassandra
Issue Type: Bug
Components: Core
Environment: ccm, dtest, cassandra-1.1. The error does not happen in
cassandra-1.0.

The following dtest command produces an error:
{code}export CASSANDRA_VERSION=git:cassandra-1.1; nosetests --nocapture
--nologcapture
concurrent_schema_changes_test.py:TestConcurrentSchemaChanges.load_test{code}
Here is the error:
{code}

{code}
For reference, here is the dtest function that causes the failure:
{code}
def load_test(self):
"""
apply schema changes while the cluster is under load.
"""
debug("load_test()")
cluster = self.cluster
cluster.populate(1).start()
node1 = cluster.nodelist()[0]
wait(2)
cursor = self.cql_connection(node1).cursor()
def stress(args=[]):
debug("Stressing")
node1.stress(args)
debug("Done Stressing")
def compact():
debug("Compacting...")
node1.nodetool('compact')
debug("Done Compacting.")
# put some data into the cluster
stress(['--num-keys=1000000'])
# now start compacting...
tcompact = Thread(target=compact)
tcompact.start()
wait(1)
# now the cluster is under a lot of load. Make some schema changes.
cursor.execute("USE Keyspace1")
wait(1)
cursor.execute("DROP COLUMNFAMILY Standard1")
wait(3)
cursor.execute("CREATE COLUMNFAMILY Standard1 (KEY text PRIMARY KEY)")
tcompact.join()
{code}
Again, the error happens on cassandra-1.1, but not on cassandra-1.0.
