[GitHub] Ben-Zvi opened a new pull request #1351: DRILL-6543: Disable Hash Join fallback, add percent_reserved_allowance_from_direct

Ben-Zvi opened a new pull request #1351: DRILL-6543: Disable Hash Join fallback, add percent_reserved_allowance_from_direct
URL: https://github.com/apache/drill/pull/1351
 
 
   (1) Turned the default for Hash Join Fallback to **false**.
   (2) Added a new option: **planner.memory.percent_reserved_allowance_from_direct**
        This new option enforces (when a query with buffered operators is run) reserving part of the Direct Memory for the non-buffered operators. It checks against the two ways to set the memory (for the buffered operators): Memory per query per node, or Percent per query.
   Also added a test for the enforcement.
