      Description

      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.
