Varun Vasudev updated YARN-1856:
--------------------------------
Attachment: YARN-1856.002.patch
bq. Could you move these constants to CGroupsHandler ? There are already some
cgroups parameter constants defined there.
Fixed.
bq. IMO, If the behavior here is unpredictable, we should simply error our here
in case both are enabled.
Fixed.
bq. We should make the fraction configurable, I think. What are the
implications of the soft limit?
Fixed. It's a lower limit useful when there's memory contention.
bq. Since we are skipping changes to yarn-default.xml (based on changes I see
in TestYarnConfigurationFields), these should be marked \@Private , similar to
how network/disk configs settings are annotated?
Fixed.
bq. Thinking aloud here : should we add support in some form for
memory.oom_control and notifications/stats?
We should take that up as a separate JIRA.
