Sunil G commented on YARN-3652: ------------------------------- Hi [~xinxianyin] This will be a very helpful feature and thanks for working on same. Few points: 1. *Throughput*: Are you mentioning about #events processed over a period of time? If so, how can we set the timeline by which throughput is calculated (configurable?)? A clear indicator from this will be like we can predict possible end timeline for the pending events in dispatcher queue. Adding throughput with #no of pending events may give much more better indication about RM overload. 2. However there are many events coming to scheduler, if possible a filter for the events based on events type may be helpful to give an accuracy for throughout and scheduling delay. > A SchedulerMetrics may be need for evaluating the scheduler's performance > ------------------------------------------------------------------------- > > Key: YARN-3652 > URL: https://issues.apache.org/jira/browse/YARN-3652 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager, scheduler > Reporter: Xianyin Xin > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
