Jacques Nadeau created DRILL-3007:
-------------------------------------

             Summary: Update Drill configuration settings to avoid mmap threshold increases
on Linux
                 Key: DRILL-3007
                 URL: https://issues.apache.org/jira/browse/DRILL-3007
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
            Reporter: Jacques Nadeau
            Assignee: Jacques Nadeau
             Fix For: 1.0.0


Because Drill uses extensive direct memory but often caches random segments, it is important
to make sure all the memory chunks are allocated as MMAP regions so Drill correctly releases
memory back to the OS.  We need to update the Drill environment variables to ensure this.
