Phoenix 5.x requires Hadoop 3. While HBase 2.x is compatible with Hadoop 3, the public Maven HBase
artifacts are built with Hadoop 2, and are not.

For this reason, when building Phoenix, you need to rebuild
HBase with Hadoop 3, and install it to the local maven repo of the build host.
With the 2.5.2 release HBase has started releasing Maven artifacts built with Hadoop3.
Where available, use the Maven artifacts with the `-hadoop3` postfix in the version,
i.e. `2.5.2-hadoop3`, and ignore the rest of this section.
For HBase 2.5, Phoenix already uses the -hadoop3 version by default.

For HBase versions where hadoop3 artifacts are not available, you need to rebuild HBase with
Hadoop 3, and install it to the local maven repo of the build host.
