Vladimir Ozerov resolved IGNITE-6883.
-------------------------------------
    Resolution: Won't Fix

Closing due to long inactivity. Distributed joins logic is to be redesigned 
soon, so tickets will be created as needed.

> Distributed sub-query support

>                 Key: IGNITE-6883
>                 URL: https://issues.apache.org/jira/browse/IGNITE-6883
>             Project: Ignite
>          Issue Type: New Feature
>          Components: sql
>            Reporter: Alin Andrei Corodescu
>            Priority: Minor
>
> Include behaviour similar to the distributedJoins flag for inner queries as 
> well (gather data from multiple nodes). 
> At the moment sub queries are run on remote nodes without being split into 
> map and reduce parts and without taking into account data residing in other 
> nodes (sometimes collocation is not possible).
> One use case when results are affected by this behaviour is when the subquery 
> contains a {code:sql}HAVING{code} clause, since the conditions can filter out 
> groups for which not all the entries are on the same node.
