ClassNotFoundException[skos]; ","status":500

[jdspersonal]

Hi, I am really interested to see a SKOS plugin for ES.

When I test with:

curl -XPOST 'http://localhost:9200/test' -d '{ "settings" : { "index" : { "analysis" : { "filter": { "skosfilter" : { "type": "skos", "skosFile": "ukat_examples.n3", "expansionType": "URI" } }, "analyzer" : { "skos" : { "type" : "custom", "tokenizer" : "keyword", "filter" : "skosfilter" } } } } }, "mappings" : { "default" : { "properties" : { "subject" : { "type" : "string", "index_analyzer" : "skos", "search_analyzer" : "standard" } } } }
}'

I get:

{"error":"IndexCreationException[[test] failed to create index]; nested: ElasticSearchIllegalArgumentException[failed to find token filter type [skos] for [skosfilter]]; nested: NoClassSettingsException[Failed to load class setting [type] with value [skos]]; nested: ClassNotFoundException[skos]; ","status":500}

Am I missing something?

Thanks

Seems like the plugin installation failed, can you check it in the logs?

[jdspersonal]

When installing I get a a positive response.

Downloading ...........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................DONE Installed analysis-skos

I checked the logs, there is no error from the plugin install.

I then try the post as before and get:

Can you please try

./bin/plugin -install  jprante/elasticsearch-analysis-skos/1.0.1

and see if it works?

[jdspersonal]

Hi, thanks for looking at this.

I installed 1.0.1 and it tells me it is installed ok with no reported errors. No problems reported in the log. I try the POST again and:

{"error":"IndexCreationException[[test] failed to create index]; nested: ElasticSearchIllegalArgumentException[failed to find token filter type [skos] for [skosfilter]]; nested: NoClassSettingsException[Failed to load class setting [type] with value [skos]]; nested: ClassNotFoundException[skos]; ","status":500}

[jprante]

I double checked, with the example you gave above, and it works here (you need to copy the n3 file with the given name before starting ES and you need to use 'default' instead of '_default' in the mapping but that is obviously due to github markdown formatting).

The error means the plugin is not installed at all. It's unable to lookup the new filter tokenizer type name 'skos'.

Can you grep your log for a 'plugins' line such as

[2012-08-15 12:28:48,076][INFO ][plugins                  ] [Copycat] loaded [analysis-combo, analysis-skos, analysis-icu], sites [head]

'analysis-skos' must be displayed. In most cases, it is the second line when starting ES with

./bin/elasticsearch -f

[jdspersonal]

OK. We are getting something different now.

Could it be an issue with another elastic search plugin?

Many thanks...

[jprante]

No, this is just a warning of SLF4j which is clever enough to continue. In case you are worried, remove one slf4j-log4j12.jar from the plugin folder.

But I think it's a version issue. I have built against 0.19.8. Can you upgrade to 0.19.8, are you really on 0.19.2?

[jdspersonal]

Hey!

I tried a fresh installation with 0.19.8. It works beautifully. Thank you for your time, and thanks for the help, and of course the plugin.

[jprante]

Thanks for your feedback, you're welcome!

[jprante]

Please open a separate issue for that. Do not capture old issues. Thanks.

I'm working on a 0.90 release.
