code for easier debugging
Paul Rogers created IMPALA-7841:
-----------------------------------
Summary: Refactor QueryStmt, other analysis code for easier debugging
Key: IMPALA-7841
URL: https://issues.apache.org/jira/browse/IMPALA-7841
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 3.0
Reporter: Paul Rogers
Assignee: Paul Rogers
IMPALA-7808 started the process of refactoring the Analyzer code for easier debugging. It did so by grouping {{SelectStmt}} code into a nested class, which then allowed breaking up a large function into smaller chunks.
This ticket continues that process with two changes:
* Follow-on refactoring of {{SelectStmt}} to make some of the newly-created functions simpler. (The first change tried to keep code unchanged as much as possible.)
* Apply the same technique to the {{QueryStmt}} base class and to its other subclasses.
