Following your instruction I have managed to run HDFS and YARN on my cluster using openJDK-8 instead of Oracle Java (is not pre-installed on Raspbian Buster and can't be installed via apt).
However, when running the wordcount example.
> yarn jar hadoop-mapreduce-examples-3.2.0.jar wordcount "/books/alice.txt" output
following error occurs
Error: Java heap space
Error: Java heap space
Error: Java heap space
and the job fails.
Do you have any idea what the reason might be?
