IMPALA-1422 introduced tests that do not work with the testing setup for hbase. Namely, tinyinttable is not defined in the functional_hbase database, but is defined in the functional database. Exhaustive tests uncovered the issue. This change makes two changes so that tests work with functional_hbase: 1) use a table that is present in both functional and functional_hbase. the tests needed a subquery result with a single int column. tinyinttable is replaced with an inline view that provides this single int column in a portable manner. 2) nulls are handled differently with hbase (see IMPALA-728) so the nulltable used in the tests is set to functional.nulltable to avoid inconsistent results across input formats. Testing: - ran e2e tests with exhaustive exploration strategy for the broken test.
