> Refactor hash expression construction in InsertLocalExchangeVisitor and PrelUtil into one place
> -----------------------------------------------------------------------------------------------
>
> Key: DRILL-2858
> URL: https://issues.apache.org/jira/browse/DRILL-2858
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Relational Operators
> Affects Versions: 0.8.0
> Reporter: Venki Korukanti
> Assignee: Venki Korukanti
> Fix For: 0.9.0
>
>
> Currently there are two place where we construct the hash expression based on the partition fields:
> 1. InsertLocalExchangeVistor (generates RexExpr type)
> 2. PRelUtil.getHashExpression (generate LogicalExpression type)
> Having this logic in two places makes them prone to errors and they can easily go out of sync causing hard to debug verification failures.
