Date Wed, 18 Oct 2017 15:14:10 GMT
Hi all,

Seeing as I couldn't get the UR template to work I decided to try my luck
with other templates. I have now tried with the Recommendation template as
downloaded from:

I'm using basically the same setup as before:

elasticsearch 1.7.6
hbase 1.2.6

And the error I get while running the integration test is the following:

Why is this happening? How can I fix this?
