Subject [jira] [Commented] (YARN-769) Add metrics for number of containers
Date Thu, 06 Jun 2013 16:03:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13677171#comment-13677171

Hitesh Shah commented on YARN-769:

[~jlowe] In that case, would it then be more correct to report available memory as calculated
by the RM to be the actual free and allocate-able memory and not the actual available memory
from the NM? i.e. assuming NM reports available as 9 GB but if the RM scheduler's min allocation
is set to 2 GB, the available memory would be reported as 8 GB instead of 9?
