Ah, sorry, I meant I hit this with Hive < 2.2.0. I have not yet tried with 
2.2.0.

[~calebjones], have you tried with latest master? You should not hit that 
limitation anymore, as we should support any arbitrary condition. Please, let 
me know if you do and the error you hit.

Caleb Jones commented on HIVE-15211:


Will UDFs be supported in complex expressions in the ON clause?

I hit this limitation when I had two tables I wanted to join on based on the 
intersection of array columns.


{noformat}
create table tbl_a (
  val string,
  ids array
);

create table tbl_b (
  val string,
  ids array
);

add jar hdfs:///brickhouse-0.7.1-SNAPSHOT.jar;

select a.val, b.val
from tbl_a as a
join tbl_b as b
on (size(intersect_array(a.ids, b.ids)) > 0);
{noformat}

Ashutosh Chauhan commented on HIVE-15211:
-

I noted catch-all condition for outer join checks. But, still I prefer to have 
checks at the point where it matters, since we know what exact limitations we 
have. However, since you are making all those restrictions go away, this wont 
matter anyway.

> Provide support for complex expressions in ON clauses for INNER joins
> -
>
> Key: HIVE-15211
> URL: https://issues.apache.org/jira/browse/HIVE-15211
> Project: Hive
>  Issue Type: Bug
>  Components: CBO, Parser
>Affects Versions: 2.2.0
>Reporter: Jesus Camacho Rodriguez

>
> Currently, we have some restrictions on the predicates that we can use in ON 
> clauses for inner joins (we have those restrictions for outer joins too, but 
> we will tackle that in a follow-up). Semantically equivalent queries can be 
> expressed if the predicate is introduced in the WHERE clause, but we would 
> like that user can express it both in ON and WHERE clause, as in standard SQL.
> This patch is an extension to overcome these restrictions for inner joins.
> It will allow to write queries that currently fail in Hive such as:
> {code:sql}
> -- Disjunctions
> SELECT *
> FROM src1 JOIN src
> ON (src1.key=src.key
>   OR src1.value between 100 and 102
>   OR src.value between 100 and 102)
> LIMIT 10;
> -- Conjunction with multiple inputs references in one side
> SELECT *
> FROM src1 JOIN src
> ON (src1.key+src.key >= 100
>   AND src1.key+src.key <= 102)
> LIMIT 10;
> -- Conjunct with no references
> SELECT *
> FROM src1 JOIN src
> ON (src1.value between 100 and 102
>   AND src.value between 100 and 102
>   AND true)
> LIMIT 10;
> {code}
