Hi everyone, I'm using Flink 0.10.2 for some benchmarks and had to add some small changes to Flink, which led me to compiling and running it myself. This is when I noticed a performance difference in the pre-packaged Flink version that I downloaded from the web ( http://archive.apache.org/dist/flink/flink-0.10.2/flink-0.10.2-bin-hadoop27.tgz) versus the form of the release-0.10 branch I built myself (mvn -Dhadoop.version=2.7.1 -Dscala-2.11 -DskipTests -Drat.skip=true clean install // mvn version 3.0.4).
I ran some version of TeraSort (https://github.com/eastcirclek/terasort) and I noticed that the pre-packaged version of Flink performs 10-20% better than the one I built myself (the only tweaks I mead are in the CliFrontend after the Job has finished running, so I would rule out bad programming on my side). Has anyone come across this before? Or could you provide me with clearer build instructions in order to reproduce the downloadable archive as closely as possible? Thanks in advance!
