-------------------------------------
Assignee: Sean Hsuan-Yi Chu
> Better error messages when no equality join is specified
> --------------------------------------------------------
>
> Key: DRILL-1325
> URL: https://issues.apache.org/jira/browse/DRILL-1325
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Affects Versions: 0.4.0
> Environment: MapR 3.1.1
> Drill 0.4.0
> CentOS 6.4
> Reporter: Hao Zhu
> Assignee: Sean Hsuan-Yi Chu
> Priority: Minor
> Fix For: 1.0.0
>
>
> Equal hash join works fine, for example:
> {code}
> > explain plan for select a.*,b.user_port
> . . . . . . . . . . . . . . . . . . . . . . .> from cp.`employee.json` a,
> sys.drillbits b

> a.position_id=b.user_port ;
> +------------+------------+
> | text | json |
> +------------+------------+
> | 00-00 Screen
> 00-01 Project(*=[$0], user_port=[$1])
> 00-02 Project(T1¦¦*=[$0], user_port=[$2])
> 00-03 HashJoin(condition=[=($1, $2)], joinType=[inner])
> 00-05 |
> +------------+------------+
> 1 row selected (0.428 seconds)
> {code}
> However if we change "=" to "<>" , it failed:

> 2. If we do not support, the error message should be more clear and simpler
> to tell something like "non-equal join is not supported in current
> version...."
