-------------------------------------
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.
