xuyangzhong opened a new pull request, #3594:
URL: https://github.com/apache/fluss/pull/3594
### Purpose
Linked issue: close #3593
The tablet server rejects writes once the data-disk usage exceeds
`server.data-disk.write-limit-ratio` (default `0.85`), and only resumes after
usage drops below `ratio - 0.10`. `FlussClusterExtension` inherits this
default,
so tests that write data through it fail with disk-write-limited errors on CI
runners or local machines whose disk usage is already above 85%. These
failures
are unrelated to the code under test and make the suite flaky and
environment-dependent.
This change makes the shared test cluster ignore disk-usage protection so
tests
no longer depend on the host's free disk space.
### Brief change log
- Set `server.data-disk.write-limit-ratio` to `0.99` in
`FlussClusterExtension`
so the disk-usage write protection effectively stays out of the way during
tests, while still guarding against a truly full disk.
- Fix the import ordering of `org.apache.curator.test.TestingServer`.
### Tests
No new tests. This only adjusts test infrastructure. Existing tests based on
`FlussClusterExtension` continue to pass and are no longer affected by the
host
disk-usage limit.
### API and Format
No. This change is limited to test utilities and does not affect any public
API
or storage format.
### Documentation
No. This is a test-only change and introduces no new feature.
