-------------------------------------------
> Refactor FrontEnd to make plan fragments available for testing
> --------------------------------------------------------------
>
> Key: IMPALA-7842
> URL: https://issues.apache.org/jira/browse/IMPALA-7842
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Impala 3.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
>
> Today, the {{FrontEnd}} class uses a functional model to generate a plan:
> pass in SQL text to the {{createExecRequest()}} method and get back a Thrift
> plan ready for serialization.
> For unit testing, however, we need access to the intermediate plan fragments
> produced by the planner. Inspecting only the Thrift version results in loss
> of important details.
> This ticket asks to create a new {{PlanCtx}} which can capture the details
> for testing.
