[jira] [Commented] (YARN-655) Fair scheduler metrics should subtract allocated memory from available memory

    [ https://issues.apache.org/jira/browse/YARN-655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13652186#comment-13652186 ] 

Sandy Ryza commented on YARN-655:
---------------------------------

Uploaded patch that subtracts allocated memory from available memory and does this synchronously instead of on the update thread so that things will stay consistent.
