mvn package # to build code
java -jar mapreduce-perf/target/benchmarks.jar
You need to have async profiler installed.
Once you have it, you need configure your operating system:
sysctl kernel.kptr_restrict=0
sysctl kernel.perf_event_paranoid=1
and run it with:
java -jar mapreduce-perf/target/benchmarks.jar -prof "async:libPath=<path to async profiler>/build/libasyncProfiler.so;output=flamegraph;event=cpu"
You can try to run it under docker with:
docker run --privileged -u $(id -u ${USER}):$(id -g ${USER}) --rm -v $(pwd):/work symentis/jvmperformance-workshop:latest java
-jar /work/target/benchmarks.jar -prof "async:libPath=/opt/async-profiler/build/libasyncProfiler.so;output=flamegraph;event=cpu"
