> Key: HIVE-3929
> URL: https://issues.apache.org/jira/browse/HIVE-3929
> Project: Hive
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 0.7.0, 0.8.1, 0.9.0, 0.10.0
> Environment: Linux
> Reporter: Dean Wampler
>
> The wiki discussion of OUTER JOINs correctly describes the behavior of WHERE
> clauses with regards to partition filters. Namely, that they don't work as
> expected, because the WHERE clause is evaluated after the join has been
> performed.
> However, the description then says that you can move these partition filters
> into the ON clause to achieve partition filtering. In fact, these filters
> have no effect.
> The only working solution I know of is to use nested SELECTS that apply the
> partition filters, then join on the results.
