> Use a different expession for ArraySegment and NamedSegment accessors
> ---------------------------------------------------------------------
>
> Key: DRILL-1680
> URL: https://issues.apache.org/jira/browse/DRILL-1680
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Reporter: Hanifi Gunes
> Assignee: Aman Sinha
> Fix For: 0.7.0
>
>
> Drill planner treats ArraySegment accessors the same way with NamedSegment
> accessors. This ambiguity causes planner to loop indefinitely when projection
> pushdown is enabled (see DRILL-1455). We need to distinctly name two
> operators that have been used to access array segments and named segments.
> Array segments should still use ITEM. However named segments should be
> accessed via some other name just like GETCOLUMN/GETFIELD.
