[jira] [Updated] (YARN-2014) Performance: AM scaleability is 10%
slower in 2.4 compared to 0.23.9
[ https://issues.apache.org/jira/browse/YARN-2014?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sangjin Lee updated YARN-2014:

> --------------------------------------------------------------------

> Key: YARN-2014
> URL: https://issues.apache.org/jira/browse/YARN-2014
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.4.0
> Reporter: patrick white
> Assignee: Jason Lowe
>
> Performance comparison benchmarks from 2.x against 0.23 shows AM scalability benchmark's runtime is approximately 10% slower in 2.4.0. The trend is consistent across later releases in both lines, latest release numbers are:
> 2.4.0.0 runtime 255.6 seconds (avg 5 passes)
> 0.23.9.12 runtime 230.4 seconds (avg 5 passes)
> Diff: -9.9%
> AM Scalability test is essentially a sleep job that measures time to launch and complete a large number of mappers.
> The diff is consistent and has been reproduced in both a larger (350 node, 100,000 mappers) perf environment, as well as a small (10 node, 2,900 mappers) demo cluster.
