com.thinkaurelius.titan.diskstorage.cassandra.thrift.CassandraThriftStoreManager.clearStorage()

Connect to Cassandra via Thrift on the specified host and port and attempt to truncate the named keyspace.

This is a utility method intended mainly for testing. It is equivalent to issuing 'truncate ' for each of the column families in keyspace using the cassandra-cli tool.

Using truncate is better for a number of reasons, most significantly because it doesn't involve any schema modifications which can take time to propagate across the cluster such leaves nodes in the inconsistent state and could result in read/write failures. Any schema modifications are discouraged until there is no traffic to Keyspace or ColumnFamilies. @throws StorageException if any checked Thrift or UnknownHostException is thrown in the body of this method
