Subject [jira] [Updated] (YARN-1856) cgroups based memory monitoring for containers
Date Tue, 08 Dec 2015 07:00:18 GMT

     [ https://issues.apache.org/jira/browse/YARN-1856?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Varun Vasudev updated YARN-1856:
--------------------------------
    Attachment: YARN-1856.003.patch

bq. The constants should have ‘MEMORY’ in their names. For example, CGROUP_PARAM_HARD_LIMIT
is better named as CGROUP_PARAM_MEMORY_HARD_LIMIT in order to avoid future collisions. This
is similar to how BLKIO is used in the previous line (classid should be fixed at some point
too)

Fixed.

bq. Is the soft limit conf setting meant to represent a percentage or is it a fraction between
0 and 1? From the default value of 0.9f and the application of the soft limit it appears to
be a fraction, but the name of the setting and its validation check seem to indicate that
it is meant to be a percentage. This needs to be fixed.

Good catch. It's meant to be a percentage. Fixed.
