[jira] [Commented] (IMPALA-5950) Q35a and Q48 test files don't
match standard qualification queries

IMPALA-5950: fix TPC-DS Q35a and Q48 queries
The query text (for Q48) and substitution parameters didn't match the
TPC-DS standard for qualification queries. After fixing that, the
queries return the results expected by the TPC-DS standards.
Note that this may affect the performance of perf workloads running
tpcds-unmodified.

>
> Results of q35a (in ttq.218.out) disagree with same query run on Postgres, Vertica and Netezza.
> Results of q48 disagree with expected TPC-DS result data. Q48 was passing for a long time, then this _intermittent_ failure began occurring at least by 10/5/2017, 16:17PT on Jenkins--see attached pre-review-consoleText.
