Description

1. The query generator should generate On-clause predicates that only reference one or the other table of a particular join, or none of the tables at all (constant predicate).

For example, the query gen should be able to generate the buggy query of IMPALA-2665.

2. The query generator should generate Having-clause predicates that only reference the GROUP BY columns of an aggregation.

For example, the query gen should be able to generate the buggy query of IMPALA-2144.
