--------------------------
Summary: Query may generate different results depending on the
number of reducers
Key: HIVE-9112
URL: https://issues.apache.org/jira/browse/HIVE-9112
Project: Hive
Issue Type: Bug
Reporter: Chao
Some queries may generate different results depending on the number of
reducers, for example, tests like ppd_multi_insert.q, join_nullsafe.q,
subquery_in.q, etc.
Take subquery_in.q as example, if we add
{noformat}
set mapred.reduce.tasks=3;
{noformat}
to this test file, the result will be different (and wrong):
{noformat}
