Review Comment:
   Hi, a kind ping from Kyuubi, we reverted to using Maven 3.8.x in Kyuubi for CI builds and local usage, to reduce side effects and easier to use.

   I mean, is it worth updating if 3.9.1 introduces small issues that we have to work around? or just wait?

   @dongjoon-hyun @steveloughran Adding `-Dmaven.resolver.transport=wagon` seems useful, as recent Java 11&17 Maven build have all finished within 1 hour and there have been no more timeouts.  Let me check for two more days

   me, I'm happy with whatever suits, just noting that 3.9.1 was unwelcome trouble for me as it ended up hurting the 3.3.5 release process -not the docker builds, which were still on a lower version, but my local dev builds blew up. joy

   @steveloughran Do you have any other questions? I am planning to close this PR and test Apache Maven 3.9.2+ in the future to check if it is possible not to add `-Dmaven.resolver.transport=wagon`. Apache Spark can continue to use 3.8.7 now.

   noted. interestingly for cutting hadoop releases i have had to turn off connection pooling so as to guarantee reliable builds (docker container having to download **/*.jar from maven central is too brittle otherwise). that's even older versions.
   
   * spark &c with fixed versions should stay on the good ones
   * if the latest version of the SBOR is happy on recent maven builds then we can reinstate in hadoop.

   Thanks for the ping. And welcome to cc me when Spark has the next attempt to use maven 3.9.x/4.x.
   I was pessimistic that whether Maven will change the default timeout as it's a default config (`aether.connector.connectTimeout=10000`) of Maven Artifact Resolver not in Maven itself. And as for Maven, it has changed to Artifact Resolver as the default resolver already, which fewer improvements we could expect from that. And we are also difficult to reduce possible timeout to maven central mirrors.

   Long time no see @srowen , thanks for your review ~
   
   I am not sure if the native http client will change the default timeout value to be same with wagon in the future. But I don't object to letting us wait and see if there will be any changes of the new version of Apache Maven :)

   Hi, after bumping to Maven 3.9.1 in Apache Kyuubi (https://github.com/apache/kyuubi/pull/4647), there are notable increasing failures in Maven builds when resolving Maven dependencies from the central mirror.
   We are trying to investigate and improve the situation in https://github.com/apache/kyuubi/pull/4692, by increasing Maven Resolver Transport connection timeout back to original default connection timeout 60000ms.
