ElasticSearch 1.2.1 crashing with langdetect installed

[Aaronaught]

Seen this on both a Windows and Linux server running ES 1.2.1 with the latest langdetect plugin installed...

First I get a slew of warnings like this:

[2014-06-18 11:48:26,535][WARN ][transport ] [Alfie O'Meggan] Registered two transport handlers for action langdetect, handlers: org.elasticsearch.action.support.single.custom.TransportSingleCustomOperationAction$TransportHandler@3872bb09, org.elasticsearch.action.support.single.custom.TransportSingleCustomOperationAction$TransportHandler@f505228

Then it crashes outright with the following message:

{1.2.1}: Initialization Failed ...
 1) NoClassDefFoundError[com/fasterxml/jackson/core/Versioned]
        ClassNotFoundException[com.fasterxml.jackson.core.Versioned]2) NoClassDefFoundError[com/fasterxml/jackson/databind/ObjectMapper]

FYI: I checked the plugin directory and the jackson-databind-2.3.3.jar file is there. It's happening on brand new servers with the latest versions of Java and ElasticSearch.

Any ideas?

Yes, a packaging error. WIll be fixed asap.

1.2.1.1 released.

N.B you should check if you have older langdetect jar in the plugins folder if you get strange messages like "Registered two transport handlers for action langdetect". Delete the old plugin version first.

Thanks for the quick fix. I definitely didn't have any old versions, there were just the 2 jars (jackson-databind and elasticsearch-langdetect) - now 4 jars after the update.

Also, kind of unrelated but you might want to fix the installation link as it points to an invalid URL. It says http://xbib.org/repository/org/xbib/elasticsearch/plugin/elasticsearch-langdetect/1.2.1.1/elasticsearch-langdetect-1.2.1.1-plugin.zip but it should actually be http://xbib.org/repository/org/xbib/elasticsearch/plugin/elasticsearch-langdetect/1.2.1.1/elasticsearch-langdetect-1.2.1.1.zip (without the -plugin at the end).

Yes, the jackson jars are the fix. The plugin assembly has also been fixed, the correct link is

http://xbib.org/repository/org/xbib/elasticsearch/plugin/elasticsearch-langdetect/1.2.1.1/elasticsearch-langdetect-1.2.1.1-plugin.zip
