upgrade to Hadoop 3.1.1 to be compatible with current HDP version

Currently, the latest version of Hadoop supported seems to be 2.7.1, so Halyard 2.2 will not work with the latest version 3.1 of Hadoop which is included in the latest HDP 3.0.1 (released already last November). This makes initial setup, testing and adoption unnecessarily hard, as you have to dig out an old version from the archive. Newer HDP versions also include Docker images which would provide an additional benefit for prototyping and quick deployment. See: https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.0.1/release-notes/content/comp_versions.html

It may be because Halyard 2.2 still uses deprecated methods (see #6), or because of the major version change, didn’t check closely.

So, creating the repository works, but opening fails:

Halyard 3.0 has been released with HDP 3.1 support.

Preliminary testing progress of the 3.0 nightly build on HDP 3.1 seems to be quite promising 😃 Please report any inconveniences observed.
