[jira] [Created] (DRILL-2421) ensure all allocators for a query are descendants of a single root

Chris Westin created DRILL-2421:
-----------------------------------

             Summary: ensure all allocators for a query are descendants of a single root
                 Key: DRILL-2421
                 URL: https://issues.apache.org/jira/browse/DRILL-2421
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
            Reporter: Chris Westin
            Assignee: Chris Westin
             Fix For: 0.9.0


In order to help improve usage tracking, allocations for a single query should all roll up to a single root.

This requires that the Foreman create that root, and label it, and then pass that along to anyone else that needs to create additional sub-allocators. The patch for DRILL-2406 introduces the creation of a new allocator in QueryContext, but this is currently a child of the Drillbit's TopLevelAllocator, violating the principle above. This is a reminder to fix that after the dependencies above are available.
