Subject [jira] [Commented] (YARN-415) Capture memory utilization at the app-level for chargeback
Date Fri, 15 Aug 2014 20:19:21 GMT

    [ https://issues.apache.org/jira/browse/YARN-415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14099050#comment-14099050

Jian He commented on YARN-415:
------------------------------

bq.   While they are running, they are reported as the metrics for the second attempt, but
when they complete, their metrics go back into the first attempt.
Because of this,  for consistency, I think we better use  getCurrentAttempt to charge finished
containers against current attempt also for work-presrving am restart?
{code}
    private static void updateAttemptMetrics(RMContainerImpl container) {
      // If this is a preempted container, update preemption metrics
      Resource resource = container.getContainer().getResource();
      RMAppAttempt rmAttempt = container.rmContext.getRMApps()
          .get(container.getApplicationAttemptId().getApplicationId())
          .getRMAppAttempt(container.getApplicationAttemptId());
{code}

> For the purpose of chargeback, I'd like to be able to compute the cost of an
> application in terms of cluster resource usage.  To start out, I'd like to get the memory
utilization of an application.  The unit should be MB-seconds or something similar and, from
a chargeback perspective, the memory amount should be the memory reserved for the application,
as even if the app didn't use all that memory, no one else was able to use it.
> (reserved ram for container 1 * lifetime of container 1) + (reserved ram for
> container 2 * lifetime of container 2) + ... + (reserved ram for container n * lifetime
of container n)
> It'd be nice to have this at the app level instead of the job level because:
> 1. We'd still be able to get memory usage for jobs that crashed (and wouldn't appear
on the job history server).
> 2. We'd be able to get memory usage for future non-MR jobs (e.g. Storm).
> This new metric should be available both through the RM UI and RM Web Services REST API.
