Pending #501 Pending another PR for 3.5.1 docs

[HeartSaVioR]

Notable changes section contain really too many issues - I tried to remove trivial and minor things based on title but there are almost 200 JIRA tickets being resolved in this version, hence still a lot... If we want to reduce the number down dramatically, I need experts' help to audit per area/module.

Hi, All. I merged the following, but it seems that we made a mistake.

• Add Apache Spark 3.5.1 docs #501

The document is generated from unknown code source instead of Apache Spark 3.5.1 tag.

• https://spark.apache.org/docs/3.5.1/
  

I reported to the dev mailing list. Let's fix this stuff first before moving forward.

PR with re-generated docs is up, #503.

@Yikun Hi, I see you're mainly maintaining apache-docker repo. The instruction in release-process is a bit hard to follow from the first-time release manager. Would you mind updating instruction in the release-process page in Apache Spark, or would you mind helping 3.5.1 to move forward with docker image? Thanks in advance!

[HeartSaVioR]

#503 is merged - I haven't heard an update on PyPi upload issue, and also haven't got response about docker image. Other things are all done.

[Yikun]

@HeartSaVioR Thanks for ping me, I will do it in next week.

[HeartSaVioR]

Thanks @Yikun !

@dongjoon-hyun @HyukjinKwon Mind taking another look as everything except docker image is ready? Please let me know if I have to ensure docker image is built before announcing release, as it is dependent on @Yikun .

@Yikun Friendly reminder on this.

[Yikun]

Sorry for late: apache/spark-docker#59

Please let me know if I have to ensure docker image is built before announcing release

From my understanding, the docker image will published after the release, especially the docker official image.

[HeartSaVioR]

Thanks @Yikun for the info! Looks like it isn't a blocker to announce the release.
Thanks @HyukjinKwon for reviewing!

Merging to asf-site.
