#12 syntax checking for 'group by' clouse.

[YoungWoo Kim]

Query1:
SELECT c1, count(*) FROM test_table1 GROUP BY c1;

Query2:
SELECT c1, count(*) FROM test_table1 GROUPBY c1;

Query1 works fine. (there are no syntax errors) but Query2 returns 'MapReduce job failed' error. I think Query2 should return a syntax error before running M/R jobs.
