> Project: Hive
> Issue Type: Bug
> Components: Query Planning
> Affects Versions: 0.13.0

> The left join query with on/where clause returns incorrect result (more rows
> are returned). See the reproducible sample below.
> Left table with data:
> {code}
> CREATE TABLE ltable (i int, la int, lk1 string, lk2 string) ROW FORMAT
> DELIMITED FIELDS TERMINATED BY ',';
> ---
> 1,\N,CD5415192314304,00071
> 2,\N,CD5415192225530,00071
> {code}
> Right table with data:
> {code}
> CREATE TABLE rtable (ra int, rk1 string, rk2 string) ROW FORMAT DELIMITED
> FIELDS TERMINATED BY ',';
> ---
> 1,CD5415192314304,00071
> 45,CD5415192314304,00072
> {code}
> Query:
> {code}
> SELECT * FROM ltable l LEFT OUTER JOIN rtable r on (l.lk1 = r.rk1 AND l.lk2 =
> r.rk2) WHERE COALESCE(l.la,'EMPTY')=COALESCE(r.ra,'EMPTY');
> {code}
> Result returns:
> {code}
> 1 NULL CD5415192314304 00071 NULL NULL NULL
> 2 NULL CD5415192225530 00071 NULL NULL NULL
> {code}
> The correct result should be
> {code}
> 2 NULL CD5415192225530 00071 NULL NULL NULL
> {code}
