ES nodes fail to start with floragunn search-guard installed

Hey guys,

I'd like to use an open source alternative to shield on my own non-work project. So I've read about floragunn search guard, but not had much luck with it.

With the plugin installed

 #plugin --list
Installed plugins:
    - search-guard

ES simply fails to start:

#service elasticsearch start
Starting elasticsearch (via systemctl):                    [  OK  ]

 #systemctl status elasticsearch
elasticsearch.service - Elasticsearch

As soon as I remove search-guard, I appear to be back in business:

#plugin --remove search-guard

I installed version 0.5. Maybe the problem is with the version I installed? I've found no version matrix on the project page on github the way I normally do on other plugin pages.

Here's the github page for the project:

Search Guard Security Plugin for ES 1.6

I didn't find a version for 1.7, so I tried the version for 1.6 hoping for backward compatibility.

Just wondering if anyone has any experience with this plugin in getting it to work under ES 1.7.1 I'm running this on CentOS 7.
