Hello everyone,

I have a problem with the installation of the plugin ElasticSearch.
So, I stepped through the instructions of the documentation, but I still have problems.

Here are my results when I start a research on Mahara in the CMD console:

Hi,

Mahara works with version 2.3.1 of elastica. 

Can you try it with that version?

To see which version Mahara works with, please refer to the file:

docs/lib/elastica/README.Mahara

Downloads can be found at :

http://elastica.io/releases/

Hello ! Thank you !

And which version of Elasticsearch ?

With the last version :

"A nonrecoverable error occurred. This probably means you have encountered a bug in the system"

And with the 1.7.3 I can't install Elastica :

"Error : Can not find or load the main class org.elasticsearch.plugins.PluginManager"

For the version 1.7.3 I install elasticsearch-0.19.11.jar and it works, but I have the same problem :

"A nonrecoverable error occurred. This probably means you have encountered a bug in the system"

Ps. Java version : "1.8.0_101"

Hi,

The Mahara wiki also has instructions on how to set up elasticsearch:

* https://wiki.mahara.org/wiki/Developer_Area/Setting_up_Elasticsearch

I've also googled your bug and came up with this:

* http://elasticsearch-users.115913.n3.nabble.com/bin-plugin-Failing-to-find-org-elasticsearch-plugins-PluginManager-td4026333.html

Which indicates it might be a permissions issue.

I currently run with version "0.90.2" of elasticsearch and don't have any issues.

My Java version is:

java version "1.7.0_101"
OpenJDK Runtime Environment (IcedTea 2.6.6) (7u101-2.6.6-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)

Hope this helps.

Cheers,

Ghada
