Steve Loughran commented on HADOOP-16358:
-----------------------------------------
Yetus is the main test runner we use for the runs; it choreographs the jenkins
runs for PRs. So any changes would have to go in there -talk to [~aw]
I don't think anyone has any fundamental issue with ARM, it's just that there's
always been ongoing difficulties trying to get the native code to work properly
across different CPUs, especially big-endian: you can search for Power, Sun
sparc and past ARM JIRAs to see that history.
A big issue here is getting people to care when a change breaks the Arm build:
if we don't care that things break then its going to atrophy in exactly the
same way that the windows test runs did. And frankly, we aren't being proactive
about dealing with jenkins run failures today
https://builds.apache.org/job/hadoop-qbt-trunk-java8-linux-x86/
So: not sure what to do here. If someone really wants to do an ARM release,
then they're going to have to get involved enough not just to set up the test
run, but get it actually working, then own the problem of making sure it still
works. Is there someone we can recruit for that
Personal note: not a fan of Zuul. Not going to block anything, but not going to
put any effort in either.
> Add an ARM CI for Hadoop
> ------------------------
>
> Key: HADOOP-16358
> URL: https://issues.apache.org/jira/browse/HADOOP-16358
> Project: Hadoop Common
> Issue Type: Improvement
> Components: build
> Reporter: Zhenyu Zheng
> Priority: Major
>
> Now the CI of Hadoop is handled by jenkins. While the tests are running under
> x86 ARCH, the ARM arch has not being considered. This leads an problem that
> we don't have a way to test every pull request that if it'll break the Hadoop
> deployment on ARM or not.
> We should add a CI system that support ARM arch. Using it, Hadoop can
> officially support arm release in the future. Here I'd like to introduce
> OpenLab to the community. [OpenLab|https://openlabtesting.org/] is a open
> source CI system that can test any open source software on either x86 or arm
> ARCH, it's mainly used by github projects. Now some
> [projects|https://github.com/theopenlab/openlab-zuul-jobs/blob/master/zuul.d/jobs.yaml]
> has integrated it already. Such as containerd (a graduated CNCF project, the
> arm build will be triggerd in every PR,
> [https://github.com/containerd/containerd/pulls]), terraform and so on.
> OpenLab uses the open source CI software [Zuul
> |https://github.com/openstack-infra/zuul] for CI system. Zuul is used by
> OpenStack community as well. integrating with OpneLab is quite easy using its
> github app. All config info is open source as well.
> If apache Hadoop community has interested with it, we can help for the
> integration.
