Josh Elser commented on PHOENIX-4968:
-------------------------------------
The goal of Phoenix5 was to work with Hadoop3. Turns out, HBase2 makes it
*really* hard to have a Maven build that works with Hadoop3. We can't use the
published HBase2 artifacts in Maven with Hadoop3 because there are incompatible
binary changes (e.g. A Hadoop class becomes an interface or vice-versa)
Getting off of Hadoop2 (and lots of old/bad dependencies it carries) need to be
addressed first by getting HBase2 onto the shaded Hadoop dependencies and some
HBase2 artifacts published that are compiled against Hadoop3.
