--------------------------------
Resolution: Fixed
> ExternalSortBatch has inconsistent notions of the memory limit
> --------------------------------------------------------------
>
> Key: DRILL-5020
> URL: https://issues.apache.org/jira/browse/DRILL-5020
> Project: Apache Drill
> Issue Type: Sub-task
> Affects Versions: 1.8.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
>
> The memory limit cases for the spill-needed test seem inconsistent:
> For the test for in-memory sort:
> {code}
> long currentlyAvailable = popConfig.getMaxAllocation() - oAllocator.getAllocatedMemory();
> {code}
> For reaching the memory limit:
> {code}
> oAllocator.getAllocatedMemory() > .95 * oAllocator.getLimit()
> {code}
> That is, one uses {{oAllocator.getLimit}} ("the current maximum limit this allocator imposes"), the other uses {{popConfig.getMaxAllocation}} ("The maximum memory this operator can allocate".)
