-----------------------------------
Summary: 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
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.
