Subject [jira] [Commented] (YARN-2225) Turn the virtual memory check to be off by default
Date Mon, 22 Feb 2016 08:28:18 GMT

    [ https://issues.apache.org/jira/browse/YARN-2225?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15156615#comment-15156615

Akira AJISAKA commented on YARN-2225:
-------------------------------------

bq. IMHO, I prefer to make the default value of the vmem ratio larger. How about closing this
issue and doing it on another jira(or, moving HADOOP-11364 to YARN issue)
Agree. Closing this issue and moving HADOOP-11364 to YARN.

> 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 DEFAULT_NM_VMEM_CHECK_ENABLED off by default
and let users turn it on if they need to.
