Jian He commented on YARN-415: ------------------------------ Hi [~eepayne], thanks for all your effort on this. Patch looks good to me overall. [~kasha], do you want to take another look ? > Capture aggregate memory allocation at the app-level for chargeback > ------------------------------------------------------------------- > > Key: YARN-415 > URL: https://issues.apache.org/jira/browse/YARN-415 > Project: Hadoop YARN > Issue Type: New Feature > Components: resourcemanager > Affects Versions: 2.5.0 > Reporter: Kendall Thrapp > Assignee: Andrey Klochkov > Attachments: YARN-415--n10.patch, YARN-415--n2.patch, > YARN-415--n3.patch, YARN-415--n4.patch, YARN-415--n5.patch, > YARN-415--n6.patch, YARN-415--n7.patch, YARN-415--n8.patch, > YARN-415--n9.patch, YARN-415.201405311749.txt, YARN-415.201406031616.txt, > YARN-415.201406262136.txt, YARN-415.201407042037.txt, > YARN-415.201407071542.txt, YARN-415.201407171553.txt, > YARN-415.201407172144.txt, YARN-415.201407232237.txt, > YARN-415.201407242148.txt, YARN-415.201407281816.txt, > YARN-415.201408062232.txt, YARN-415.201408080204.txt, > YARN-415.201408092006.txt, YARN-415.201408132109.txt, > YARN-415.201408150030.txt, YARN-415.201408181938.txt, > YARN-415.201408181938.txt, YARN-415.201408212033.txt, YARN-415.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
