-----------------------------------
Summary: Turn the virtual memory check to be off by default
Key: YARN-2225
URL: https://issues.apache.org/jira/browse/YARN-2225
Project: Hadoop YARN
Issue Type: Bug
Reporter: Anubhav Dhoot
The virtual memory check may not be the best way to isolate applications.
Virtual memory is not the constrained resource. It would be better if we limit
the swapping of the task using swapiness instead. This patch will turn this off
by default and let users turn it on if they need to.
