Ryu Kobayashi updated HIVE-27088:
---------------------------------
Description:
When hive.merge.nway.joins is set to `true` and JOIN is performed with INNER
and OUTER and a filter exists, normal results cannot be obtained.
For example:
{code:java}
FROM a
INNER JOIN b
ON a.id = b.id
AND (a.code = 1 or a.code = 2)
LEFT OUTER JOIN c
ON a.id = c.id{code}
I think this is also related to the next ticket:
https://issues.apache.org/jira/browse/HIVE-21322
was:When `hive.merge.nway.joins` is set to true and JOIN is performed with
INNER and OUTER and a filter exists, normal results cannot be obtained.
> Using MergeJoin and using filters does not work
