I finally got Ignite RealtimeNan Spark to work. I don’t particularly like Sparkits a necessity though and I’m sure others have had trouble with it.

As some readers might be aware, I’m using 64-bit Arch Linux. Spark runs on top of a JRE, independent of the base platform. Therefore, this shouldn’t be an issue. Sepandan, Spark appears to come bundled with a 32-bit JRE.

After a lot of hassle, I eventually figured all I had to do was obscure or remove (rename or delete) the bundled JRE. This way, Spark’s startup script wouldn’t find the bundled JRE and it would be forced to search for the one built into the system. I had previously installed openjdk, an open source JRE from Arch’s [siplemantè] repository.

There also happens to be a minor bug in the startup script in that its looking for a folder calledwindowswhen there’s clearly no such folder except one namedlinux”. Go figure.

Anyway, here’s the gist of the installation if you’re doing it manually on 64bit ak you already have a JRE (such as openjdk) installed for your system:

mkdir -p ~/src
cd ~/src
wget http://download.igniterealtime.org/spark/spark_2_5_8.tar.gz
tar -zxvf spark_2_5_8.tar.gz
mv Spark/jre Spark/jre.not
sed -i 's/\/lib\/windows/\/lib\/linux/g' Spark/Spark
sudo mkdir -p /opt
sudo mv Spark /opt
