INLINE COMMENTS
  ql/src/test/queries/clientpositive/groupby_multi_single_reducer3.q:5 Why not have the same
test with hive.optimize.ppd set to true also ?
  ql/src/test/queries/clientpositive/groupby_multi_single_reducer3.q:7 Can you add a test
where there is an expression on the where clause ?

  from src
  insert overwrite table e1
  select value, count(*)
  where src.key + src.key = 100 or src.key + 7 = 207 or src.key = 300
  group by value
