-user@ on purpose We have previously communicated that hbase drops support for EOM Hadoop releases in the next hbase minor release. So I don't think we need specific communication about Hadoop 2.8.
I am +1 on updating branch-2 to 2.9 or 2.10. I don't have strong feelings on if that includes the change landing in hbase 2.3.0, but I think this is the kind of ongoing maintenance work that should happen sooner rather than later, so maybe time for branch-2.3 if we don't want the update there.
