Resolution: Fixed
> Refactor "managed" external sort for unit tests

> Key: DRILL-5342
> URL: https://issues.apache.org/jira/browse/DRILL-5342
> Project: Apache Drill
> Issue Type: Sub-task
> Components: Tools, Build & Test
> Affects Versions: 1.10.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Fix For: 1.11.0

>
> The external sort was heavily refactored in 1.10 to allow adding memory
> management. (See DRILL-5080.) That effort focused on breaking up the large
> functions into smaller chunks to allow us to more easily modify the bits
> relevant to adding memory management.
> This ticket discusses refining those changes to create modular bits that can
> be unit tested individually. For the most part, code will remain unchanged
> functionally, but functions will shift from class to class to break
> dependencies. Also, interfaces will be narrowed to remove global dependencies
> on things like {{FragmentContext}} or {{OperatorContext}}.
> The code reviewer(s), when using GitHub, will simply see large changes. Notes
> below identify what was actually changed vs. what was merely moved.
