[this]

What changes were proposed in this pull request?

This PR upgrades Jetty version to 9.4.44.v20210927.

Why are the changes needed?

We would like to have the fix for jetty/jetty.project#6973 in latest Spark.

Does this PR introduce any user-facing change?

No

How was this patch tested?

CI

[srowen]

I think you need to run the dev/test-dependencies.sh --replace-manifest script

[AmplabJenkins]

Can one of the admins verify this patch?

[srowen]

Hm. The tests fail for unrelated reasons (can't download some library?), and I tried re-running them, but seems like the same result. Eh, hm, does anyone else know how to kick this properly?

[HyukjinKwon]

Ah, only the PR author can kick the build at https://github.com/this/spark/runs/4844562933 .. one workaround for committers is to manually push an empty commit. this is the limitation in the current CI implementation 😢

FYI I have restarted the build job.

My 3rd attempted passed https://github.com/this/spark/runs/4869742406?check_suite_focus=true. However that is not reflected here in the checks list. Do I need to push an empty commit to re-trigger a new build or is this enough?

[srowen]

Yep all green now. I will merge to master

@srowen Do we need to port this to the branch-3.2branch?

[srowen]

Possible, how much does this affect spark users? Generally wouldn't back port anything but non trivial bug fixes

@srowen Not much, Ack.

[JackBuggins]

@srowen @this I would certainly pick up this update if it was made available against branch-3.2. Are there any strong objections to me raising a PR for it?

[HyukjinKwon]

Is there any significant bug that affects Spark directly?

[JackBuggins]

None to my knowledge @HyukjinKwon, but wrt jetty/jetty.project#6973, my thinking is it would offer peace of mind

[dongjoon-hyun]

In general, the dependency change on the release branch is -1 by default if there is no significant needs, @JackBuggins .
