The Hadoop community has started to discuss a 3.3.0 release. http://mail-archives.apache.org/mod_mbox/hadoop-hdfs-dev/201908.mbox/%3CCAD%2B%2BeCneLtC%2BkfxRRKferufnNxhaXXGa0YPaVp%3DEBbc-R5JfqA%40mail.gmail.com%3E
While still early, it wouldn't hurt to start exploring what's coming in Hadoop 3.3.0. In particular, there are a bunch of new features that brings in all sorts of new dependencies.
I will use this Jira to list things that are related to Hadoop 3.3.0.
