Until 2018, I published comparisons of the supported versions of components in the multiple available Hadoop distributions. Those older posts showed the ebb and flow of new additions to the typical stack supported by “most” distributors slowed to a halt after everyone (mostly) added Kafka. The relative version currency was fairly stable, with Hortonworks typically first to market with many of the newest Apache versions and Cloudera often close behind and leading on some where they were more dominant on the project committee.
