cool, thanks all! to sum up the discussion: HBase 2.0 will have 2.6.1+ and 2.7.1+ has supported hadoop version. (hadoop 3.x support will be decided later, since work is still going on)
HBASE-16884 - updates the supported version map in the docs, with the 2.6.1+ and 2.7.1+ support for 2.0 HBASE-16887 - fixes pre-commit to run with 2.6.1+, 2.7.1+, 3.0 on master (hbase 2.0) and 2.4.0+, 2.5.0+, 2.6.1+, 2.7.1+ on other branches.
