Hive 3.0 make a few function calls that depend on Hadoop 3.x, but they are easy to replace with code that compiles okay on Hadoop 2.8+. I am currently running Hadoop 3.x on Hadoop 2.7.6 and HDP 2.6.4 to test with the TPC-DS benchmark, and have not encountered any compatibility issue yet. I previously posted a diff file that lets us compile Hadoop 3.x on Hadoop 2.8+.
