Building Cassandra 3.10 for IBM S390X (RHEL 7.2)

The other day I was given a task to build Apache Cassandra 3.10 from source on an IBM LinuxONE instance. These instances aren’t like regular VPS hosted by other services. These VPS instances run on IBM’s S390X architecture. The instances I was using are running Red Hat 7.2. Unfortunately, I don’t have any licenses for RHEL, so I made due with the free packages available.

I was following some instructions found here. At first, cassandra would fail because of some hotspot_compiler error. I originally thought it was because I was using OpenJDK instead of IBM JDK. This was a wrong assumption. Use OpenJDK for this. The real problem was caused by byteman-install-3.0.3 not being downloaded properly. I had to manually download it and include it in the Maven caches. This was shown in the before mentioned instructions. Once this was done, I could build cassandra, but when running ./bin/cassandra -f I was getting a StackOverflow error.

After some searching online, I was led to this site which hinted at changing the default JVM stack size from 256k to 512k. After doing this, cassandra worked no problem!

I hope this helps someone! I’ve included a script below that automates this whole process if you copy it into a shell script. It’s probably a little inefficient, but it gets the job done.

## Remove old JDK packages (if any)
sudo yum -y remove java-1.8.0-openjdk.s390x java-1.8.0-openjdk-devel.s390x java-1.8.0-openjdk-headless.s390x java-1.8.0-ibm.s390x java-1.8.0-ibm-devel.s390x

## Install JDK packages
sudo yum -y install git which java-1.8.0-openjdk-devel.s390x gcc-c++ make automake autoconf libtool libstdc++-static tar wget patch words libXt-devel libX11-devel texinfo

## Make /data/db directory
mkdir /data/db
cd /data/db

## Get latest version of ANT (1.10.1 as of 3/21/17)
tar -xvf apache-ant-1.10.1-bin.tar.gz

## Set some environmental variables
export LANG="en_US.UTF-8"
export JAVA_TOOL_OPTIONS="-Dfile.encoding=UTF8"
export JAVA_HOME=/usr/lib/jvm/java #(for RHEL)
export ANT_OPTS="-Xms4G -Xmx4G"
export ANT_HOME=/data/db/apache-ant-1.10.1
export PATH=$PATH:$ANT_HOME/bin

## Get latest version of Snappy
cd /data/db/
git clone
cd snappy-java
git checkout develop

## Build Snappy

## Get latest version of JNA
cd /data/db/
git clone

## Build JNA
cd jna

## Get latest version of Cassandra (3.10 as of 3/21/17)
cd /data/db/
git clone
cd cassandra
git checkout cassandra-3.10

## Build cassandra (this will fail but that's okay for now)
cd /data/db/cassandra

## Move local builds of Snappy and JNA to our cassandra build folder
rm /data/db/cassandra/lib/snappy-java-
rm /data/db/cassandra/lib/jna-4.0.0.jar
cp /data/db/snappy-java/target/snappy-java-1.1.3-SNAPSHOT.jar /data/db/cassandra/lib/snappy-java-1.1.3.jar
cp /data/db/jna/build/jna.jar /data/db/cassandra/lib/jna.jar

## Get byteman-install-3.0.3 manually
cd /tmp/
unzip -d /tmp

## Remove existing byteman
rm -f /data/db/cassandra/build/lib/jars/byteman-install-3.0.3.jar

## Copy good version of byteman to cassandra directory and Maven repo
cp /tmp/byteman-download-3.0.3/lib/byteman-install.jar /data/db/cassandra/build/lib/jars/byteman-install-3.0.3.jar
cp /tmp/byteman-download-3.0.3/lib/byteman-install.jar /home/linux1/.m2/repository/org/jboss/byteman/byteman-install/3.0.3/byteman-install-3.0.3.jar

## Rebuild Cassandra with all the correct libraries
## Notice that we don't run 'ant realclean'. This would overwrite the manual binaries we just copied
cd /data/db/cassandra

## Adjust JVM Option of Per-thread stack size from 256K to 512K to prevent StackOverflow (hint from
sed -i 's/-Xss256k/-Xss512k/g' /data/db/cassandra/conf/jvm.options

## run Cassandra in foreground and watch for errors if any
cd /data/db/cassandra/
./bin/cassandra -f
