steveloughran opened a new pull request, #6596:
URL: https://github.com/apache/hadoop/pull/6596
### Description of PR
Adds new test which can be explicitly launched to try and trigger rename
throttling.
### How was this patch tested?
It doesn't generate enough load at least when executed outside of azure
infrastructure.
I'm not sure the best way to go here. I think ideally I'd actually like an
azure storage a/c with significantly lower capacity than the default 10K IOPS
so as validate resilience better
### For code changes:
- [X] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
licensed in a way that is compatible for inclusion under [ASF
2.0](http://www.apache.org/legal/resolved.html#category-a)?
- [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`,
`NOTICE-binary` files?

> Priority: Major
>
> I need a load test to verify that the rename resilience of the manifest
> committer actually works as intended
> * test suite with name ILoadTest* prefix (as with s3)
> * parallel test running with many threads doing many renames
> * verify that rename recovery should be detected
> * and that all renames MUST NOT fail.
> maybe also: metrics for this in fs and doc update.
> Possibly; LogExactlyOnce to warn of load issues
