try {
Cluster cluster = clusterContext.getClient();
Keyspace ks = cluster.getKeyspace(keySpaceName);
// Not a big deal if Keyspace doesn't not exist (dropped manually by user or tests).
// This is called on per test setup basis to make sure that previous test cleaned
// everything up, so first invocation would always fail as Keyspace doesn't yet exist.
if (ks == null)
return;

ks.truncateColumnFamily(new ColumnFamily<Object, Object>(cf.getName(), null, null));
