Catmandu::Importer::MARC is provided by libcatmandu-marc-perl which is in
Jessie already.

That's not really my code's fault :) you may need to configure elasticsearch
before it starts. Don't forget to change the clustername in
/etc/elasticsearch/elasticsearch.yml, otherwise you may have it clustering with
other ES instances on the same network.

This said, it shouldn't just sit there if the daemon isn't available, I've
added a note to look into that.

Yep, that there is your issue.

$ curl -X GET http://koha-es:9200/

Try the one from the official repo, I'm not sure what differences are in the
debian provided version. It might just be you need some log4j stuff, but I can
only guess.
