The question isn't whether there are people running Hadoop 1.x, it is whether those people are likely to install a new version of Hive running on their old Hadoop cluster. As a point of reference, CDH 4 shipped Hadoop 2.0 and Hive 0.10 and HDP 2.0 shipped Hadoop 2.0 and Hive 0.12. > Perhaps we can declare it deprecated in some future release (perhaps 1.3), > then another release to formally remove it, as was done in HBase. Are you interested in managing a Hadoop 1.x compatible version of Hive? Maybe we should call the new release Hive 2.0 and enable you to maintain the Hive 1.x branch with backwards compatibility with Hadoop 1.x. That would enable the rest of the Hive community to move forward and take advantage of the powerful new features in Hadoop 2.x. .. Owen --089e01182f72fb881b0514d4259d--
