MartijnVisser opened a new pull request, #28630:
URL: https://github.com/apache/flink/pull/28630
## What is the purpose of the change
Backport of #28624 (clean cherry-pick).
The nightly `cron_snapshot_deployment_binary` and
`cron_snapshot_deployment_maven` jobs run on Microsoft-hosted `ubuntu-24.04`
agents that start with only ~16 GB free; the multi-JDK CI image, the restored
Maven cache and the near-full dist build push disk usage to the brink of
failure. Every other hosted-agent template already runs
`tools/azure-pipelines/free_disk_space.sh` as its first step;
`build-nightly-dist.yml` is the one that never got it.
## Brief change log
- Run `free_disk_space.sh` (with `target: host`, since the jobs run inside
the build container) as the first step of both jobs in
`tools/azure-pipelines/build-nightly-dist.yml`
## Verifying this change
This change is a trivial rework / code cleanup without any test coverage.
Verified by the next scheduled nightly run on this branch: the "Free up disk
space" step should succeed in both `cron_snapshot_deployment` jobs and the
low-disk-space warnings should disappear from the build timeline.
