Hi, As discussed in last to last week's weekly sync, I want to put forward this point on our mailing list also. Since with 0.5.1 release, we have upgraded spark to 2.4 in our master branch, we are facing difficulties after rebasing our codebase with master. At our organisation we are using spark 2.3.2 cluster in production and spark 2.3 to 2.4 upgrade has breaking changes.
So I wanted to know if any workaround is possible to bring back support for spark 2.3? I am sure there are other guys/organisations using Hudi who are not yet on spark 2.4. We really do not want to miss out on any of the cool features being developed by the community.
