Change subject: IMPALA-7842: Make query fragments available for unit testing ...................................................................... IMPALA-7842: Make query fragments available for unit testing 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 fix introduces a new planner context (PlanCtx) class that passes information into the planner, and can pass the plan fragments back out. There is no functional change, just a refactoring of the existing code. The changes also introduces a new test case that uses this feature to verify plan cardinality. Tests: The new test case demonstrates the functionality.
