Subject [jira] [Commented] (YARN-3652) A SchedulerMetrics may be need for evaluating the scheduler's performance
Date Wed, 27 May 2015 01:08:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-3652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14560252#comment-14560252

Xianyin Xin commented on YARN-3652:
-----------------------------------

Thanks [~vinodkv]. 
When i said YARN-3293 and {{SchedulerMetrics}} are similar, i mean the two are similar on
function design, and it is not implemented yet at that time. A simple {{SchedulerMetrics}}
was introduced in YARN-3630, where a {{#ofWaitingSchedulerEvent}} metric was used to evaluate
the load of the scheduler.
[~vvasudev], hope for your idea. :)

> As discussed in YARN-3630, a {{SchedulerMetrics}} may be need for evaluating the scheduler's
performance. The performance indexes includes #events waiting for being handled by scheduler,
the throughput, the scheduling delay and/or other indicators.
