How to compile Nutch 2.3.1 with Hbase 1.2.6

Question

I have to setup hadoop stack with Nutch 2.3.1. Supported version of Hbase for hadoop 2.7.4 is 1.2.6 that I have configured and tested successfully. But when I compile Nutch I got following and crawl a sample page I got this error.

According to my search such as this and this, Hbase 1.x can be compiled for Nutch 2.3.1. But How to compile I have no idea. Can someone please guide (steps etc.)

Apache Gora 0.7 is the one supporting HBase 1.2.3(+): https://issues.apache.org/jira/browse/GORA-443

You can take a look at https://stackoverflow.com/a/39837926/582789 where I wrote how to modify Nutch 2.3.1 to work with Apache Gora 0.7. About the patch https://paste.apache.org/jjqz in that answer, use "0.7" where it shows "0.7-SNAPSHOT".

By the way, Apache Gora 0.8 was released yesterday :) Just changing 0.7 for 0.8 should work.
