Subject [jira] [Commented] (YARN-3652) A SchedulerMetrics may be need for evaluating the scheduler's performance
Date Tue, 19 May 2015 01:04:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-3652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14549600#comment-14549600

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

Hi [~vinodkv], YARN-3293 and {{SchedulerMetrics}} are similar except that they focus on different
points. Should we just leverage the existed {{SchedulerHealth}} and add the performance metrics
into it?

> 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.
