Sangjin Lee updated YARN-2014: ------------------------------ Unless the patch is ready to go and the JIRA is a critical fix, we'll defer it to 2.6.2. Let me know if you have comments. Thanks! > Performance: AM scaleability is 10% slower in 2.4 compared to 0.23.9 > -------------------------------------------------------------------- > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
