I have to load ElasticSearch plugins with the offline instructions but it looks like I am getting a permissions error even when I open up permissions to the files completely and running as root! I've removed and reinstalled as well but this error is consistent. 

```
[root@ip-10-94-146-130 bin]# ./plugin install file:///home/jmblnvr/shield/license-2.1.0.zip
