Dear Apache Oozie devs, Recently I've tried to build Oozie on Linux Ubuntu 20.04 ARM64 [1]. There were two small issues but after some debugging I was able to fix them and build it successfully!
As a Java application Oozie should run on any of the supported platforms by JDK/JRE! This is true until the application uses native libraries. In Oozie's case the problem was an old version of snappy-java library coming as a transitive dependency of Apache Spark. The second issue was due to too new version of Python (3.9.5). It seems PySpark does not support it yet. Since Linux ARM64 is more and more being used on the server/cloud I'd like to ask Oozie devs whether you are interested adding Jenkins agent that will test the commits/patches or even run periodically (e.g. nightly/weekly) to prevent regressions when updating dependencies and to give some confidence to Oozie users that they could deploy it on such platform. Disclaimer: I work for OpenLab Testing (https://docs.openlabtesting.org/) and we could donate a Linux ARM64 VM that could be used as Jenkins agent for long term usage! Several other Apache projects already use such VMs, e.g. Hadoop, Cassandra, Kafka, Mesos, ... Other projects use TravisCI for testing on arm64/ppc64/s390x. In case you prefer TravisCI then I could help with a patch adding .travis.yml to Oozie! 1. https://issues.apache.org/jira/browse/OOZIE-3639 Regards, Martin
