> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Relational Operators
> Affects Versions: 1.1.0
> Reporter: Aman Sinha
> Assignee: Deneche A. Hakim
> Fix For: 1.2.0

> For a query of the following pattern:
> {code}
> alter session set `planner.enable_hashjoin` = false;
> alter session set `planner.width.max_per_node` = 6;
> select
> t1.c1, t1.c2....t1.c50
> from t1 left outer join t2 on ..
> left outer join t3 on ...
> left outer join t4 on ...
> left outer join t5 on ...
> where t2.col between t1.c1 and t1.c2
> {code}
> we get an NPE below. The dataset is large so I cannot attach it here. Will
> try to get a repro with smaller data.
> {code}
