> recognize transitivity of predicates on join keys
> -------------------------------------------------
>
> Key: HIVE-1989
> URL: https://issues.apache.org/jira/browse/HIVE-1989
> Project: Hive
> Issue Type: Improvement
> Components: Query Processor
> Affects Versions: 0.6.0
> Reporter: John Sichi
> Assignee: Charles Chen
> Fix For: 0.8.0
>
> Attachments: HIVE-1989v1.patch, HIVE-1989v4.patch,
> HIVE-1989v5-WITH-HIVE-2382v1.patch, HIVE-1989v6-WITH-HIVE-2383v1.patch,
> HIVE-1989v8.patch
>
>
> Given
> {noformat}
> set hive.mapred.mode=strict;
> create table invites (foo int, bar string) partitioned by (ds string);
> create table invites2 (foo int, bar string) partitioned by (ds string);
> select count(*) from invites join invites2 on invites.ds=invites2.ds where
> invites.ds='2011-01-01';
> {noformat}
> currently an error occurs:
> {noformat}
> Error in semantic analysis: No Partition Predicate Found for Alias "invites2"
> Table "invites2"
> {noformat}
> The optimizer should be able to infer a predicate on invites2 via
> transitivity. The current lack places a burden on the user to add a
> redundant predicate, and makes impossible (at least in strict mode) join
> views where both underlying tables are partitioned (the join select list has
> to pick one of the tables arbitrarily).
