Hadoop 2.8.x has been removed from the download page of hadoop so I think it is time to bump the hadoop dependency to 2.9.x, on master an branch-2.
And the hadoop community is going to make 2.10.x the last minor release line for 2.x https://lists.apache.org/thread.html/cab84265d632b90d66dcd1ad957a7439a2c76a987c7e62feafb4812e%40%3Ccommon-dev.hadoop.apache.org%3E I think this is a sign that the community is moving forward to 3.x. So I propose we make the master branch hadoop3 only, This requires changing the pom a bit to active hadoop3 profile by default and remove the hadoop2 profile. Thoughts? Thanks.
