@jihoonson, Thank you for your review :)
There are some problems.
Actually, in Tajo,
1. Client Side Var is not working with ResultSet now.
Because, getCliSideVar() and getClientSideSessionVars() see different
vairable map;
2. in "SET TIME ZONE 'GMT+1' case
It is parsed and executed in Server Side. but in tajo, There is no ability
to set client side var from server.
so, currently, SET TIME ZONE commands just set TIMEZONE into Server Side
Variable.
That's why I just change TIMEZONE as Server Side Var.
