### Change Logs There is a gap in the current spark driver/executor model with spark where the executor fetches jars passed in --conf spark.jars=... but these hudi cannot load classes from these jars due to the way that the SystemClassLoader has been restricted in Java 17. This means if the user specifies custom payloads in the jar they provide to spark.jars, it must exist on the class path BEFORE the JVM starts. More context for why the current logic is like this can be found here: https://github.com/apache/hudi/pull/3535 ### Impact Adds a config to allow for loading classes using thread context class loader instead of system class loader. ### Risk level (write none, low medium or high below) Medium ### Documentation Update _Describe any necessary documentation update if there is any new feature, config, or user-facing change. If not, put "none"._ - _The config description must be updated if new configs are added or the default value of the configs are changed_ - _Any new feature or user-facing change requires updating the Hudi website. Please create a Jira ticket, attach the ticket number here and follow the [instruction](https://hudi.apache.org/contribute/developer-setup#website) to make changes to the website._ ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Change Logs and Impact were stated clearly - [ ] Adequate tests were added if applicable - [ ] CI passed -- This is an automated message from the Apache Git Service.
