[jira] [Created] (YARN-3432) Cluster metrics have wrong Total
Memory when there is reserved memory on CS
Thomas Graves created YARN-3432:
-----------------------------------
Summary: Cluster metrics have wrong Total Memory when there is reserved memory on CS
Key: YARN-3432
URL: https://issues.apache.org/jira/browse/YARN-3432
Project: Hadoop YARN
Issue Type: Bug
Components: capacityscheduler, resourcemanager
Affects Versions: 2.6.0
Reporter: Thomas Graves
I noticed that when reservations happen when using the Capacity Scheduler, the UI and web services report the wrong total memory.
For example. I have a 300GB of total memory in my cluster. I allocate 50 and I reserve 10. The cluster metrics for total memory get reported as 290GB.
This was broken by https://issues.apache.org/jira/browse/YARN-656 so perhaps there is a difference between fair scheduler and capacity scheduler.
