> Currently, we try to support multiple sessions in SQL within a Spark Context, but it's broken and not complete.
> We should isolate these for each session :
> 1) current database of Hive
> 2) SQLConf
> 3) UDF/UDAF/UDTF
> 4) temporary table
> For added jar and cached tables, they should be accessible for all sessions.
