>                 URL: https://issues.apache.org/jira/browse/DRILL-2479
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Query Planning & Optimization
>    Affects Versions: 0.8.0
>            Reporter: Aman Sinha
>            Assignee: Aman Sinha
>             Fix For: 0.9.0

> The following correlated EXISTS query gives a CannotPlanException : 
> {code}
>  select count(*) from lineitem l where exists (select ps.ps_suppkey from partsupp ps
where ps.ps_suppkey = l.l_suppkey and ps.ps_partkey in (select p.p_partkey from part p));
> {code}
> The query succeeds if the IN clause in the EXISTS subquery is removed or replaced with
an IN list of constants.  It also succeeds on the latest version of Calcite.  Drill is quite
out of date with Calcite and there were decorrelation related changes in Calcite sometime
mid to late 2014.  This issue should get resolved once Drill is rebased on recent Calcite.
