Vinod Kumar Vavilapalli moved HADOOP-10553 to YARN-2014: -------------------------------------------------------- Affects Version/s: (was: 2.4.0) 2.4.0 Key: YARN-2014 (was: HADOOP-10553) Project: Hadoop YARN (was: Hadoop Common) > 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 > > 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 (v6.2#6252)
