> Currently one can not call a temp table twice from within the same hive query.
> Typically if the Hive query contains these, it can be rewritten to remove the second reference to the table. Some systems, like Tableau, generate hive queries the contain these types of un-optimized queries, that could not be used by Spark.
> The SQL engine for Spark should be able to handle two calls to the same temp table from within a single query.
