cacheTable uses a special columnar caching technique that is optimized for SchemaRDDs. It something similar to MEMORY_ONLY_SER but not quite. You can specify the persistence level on the SchemaRDD itself and register that as a temporary table, however it is likely you will not get as good performance.
