> 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
