Often in an aws emr cluster I will want to check what exactly is going on.. here is a little script that automates installing perf in any cluster node.

install-perf-on-ec2.sh

#!/bin/sh

# Author: Shlomi Vaknin
# Install perf with java flamegraphs on amazon ec2 instances

# let yarn using be able to sudo
sudo -s
echo "yarn ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

# install required packages
yum -y install git perf cmake

# install flamegrahs and java agent
su - yarn
git clone https://github.com/jrudolph/perf-map-agent.git
git clone https://github.com/brendangregg/FlameGraph.git

# Some initial settings
export FLAMEGRAPH_DIR=~/FlameGraph
export JAVA_HOME=/usr/lib/jvm/java-1.8.0
cd ~/perf-map-agent
cmake .
make

cd ~/perf-map-agent/bin

# fix some silly java bug
sed -i -e 's/\&\& java/\&\& $JAVA_HOME\/bin\/java/g' create-java-perf-map.sh

# Some extra settings
export PERF_FLAME_OPTS="--color=java --width 1900 --title=$HOSTNAME"

echo pwd
echo "Run with"
echo "PERF_RECORD_SECONDS= 15 PERF_RECORD_FREQ= 99 ./perf-java-flames <pid> -a"
