didnt work in es0.19.11

[goog]

Hi, jprante! I got this in es0.19.11

{"error":"IndexCreationException[[test] failed to create index]; nested: ElasticSearchIllegalArgumentException[could not instantiate SKOS engine]; nested: IOException[Cannot create directory: /ukat_examples.n3]; ","status":500}

the plugin starts up ok, and i have copy the file to es root directory or does it need some prerequisition?

[jprante]

Check your settings, Cannot create directory: /ukat_examples.n3 is obviously not the path you want to access. Fix it with the parameter path and skosFile.

[goog]

this is the setting pasted to bash

curl -XPOST 'http://localhost:9200/test' -d '{
  "settings" : {
     "index" : {
        "analysis" : {
            "filter": {
                "skosfilter" : {
                    "type": "skos",
                    "path": "/home/googcheng/",
                    "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"
         }
       }
     }
  }
}'

error:

{"error":"IndexCreationException[[test] failed to create index]; nested: ElasticSearchIllegalArgumentException[could not instantiate SKOS engine]; nested: NoSuchDirectoryException[file '/home/googcheng/ukat_examples.n3' exists but is not a directory]; ","status":500}

[jprante]

The skosFile parameter is also possible with giving a URI, please use

curl -XPOST 'http://localhost:9200/test' -d '{
      "settings" : {
         "index" : {
            "analysis" : {
            "filter": {
                "skosfilter" : {
                    "type": "skos",
                    "skosFile": "file:///home/googcheng/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've got the same problem as goog. It's seems that you try to reuse the same indexDir variable in different manner. On time it's a directory, one time it's a file...

[damageco]

Ok, I've finnaly understood what happend. I think goog and me using the .DEB distro of Elasticsearch. In this version ES is running under a dedicaded user and can't create a directory for the concepts indexes.
If been successfull using this commands under /var/lib/elasticsearch directory :
sudo mkdir skos/concepts_indexes
sudo mkdir skos/thesaurus
mv ukat_examples.n3 skos/thesaurus/
mkdir skos/concepts_indexes/ukat_examples.n3
sudo chown -R elasticsearch:elasticsearch skos
and the following sh file in my home directory :

curl -XPOST 'http://localhost:9200/test' -d '{
  "settings" : {
     "index" : {
        "analysis" : {
            "filter": {
                "skosfilter" : {
                    "type": "skos",
                    "skosFile": "/var/lib/elasticsearch/skos/thesaurus/ukat_examples.n3",
                    "path": "/var/lib/elasticsearch/skos/concepts_indexes/",
                    "expansionType": "URI"
                }
            },
