Registering a custom analyzer and using it in a template

Question

I am trying to add a custom analyzer to elasticsearch in order to use it as the default analyzer in the index template. So far, I could have made it work when explicitly defined as an analyzer for a property (if it is defined inside a template), but not when trying to use it by default. Here is what I still have:

Added to elasticsearch.yml:

### custom analyzer ###
index:
    analysis:
        analyzer:
            custom_whitespace:
                type: standard
                tokenizer: whitespace
                filter: [lowercase]

Elasticsearch starts without errors, but when I try to use a template to create an index, for example:

{
    "aliases": {},
    "order": 0,
    "settings": {
        "index.analysis.analyzer.default.stopwords": "_none_",
        "index.analysis.analyzer.default.type": "custom_whitespace",
        "index.refresh_interval": "5s"
    },
    "template": "goldstone-*",
    "mappings": {
        "_default_": {
            "_timestamp": {
                "enabled": true,
                "path": "@timestamp"
            },
            "_source": {
                "enabled": true
            },
            "properties": {
                "@timestamp": {
                    "type": "date"
                }

            }
        }
    }
}

When creating an index, an error occurs:

IndexCreationException[[goldstone-2014.05.05] failed to create index]; nested: ElasticsearchIllegalArgumentException[failed to find analyzer type [custom_whitespace] or tokenizer for [default]]; nested: NoClassSettingsException[Failed to load class setting [type] with value [custom_whitespace]]; nested: ClassNotFoundException[org.elasticsearch.index.analysis.customwhitespace.CustomWhitespaceAnalyzerProvider]

                    "tokenizer": "whitespace"
                }
            }
        },

        "keystone_service_list": {
            "_timestamp": {
                "enabled": true,
                "path": "@timestamp"
            },
            "_source": {
                "enabled": true
            },
            "properties": {
                "@timestamp": {
                    "type": "date"
                },
                "region": {
                    "type": "string",
                    "analyzer": "custom_whitespace"
                }
            }
        }
   }
}

dynamic-templates, :

// only show 'mappings' part
"mappings": {
    "keystone_service_list": {
        "_timestamp": {
                "enabled": true,
                "path": "@timestamp"
            },
            // _source enabled default
            //"_source": {
            //    "enabled": true
            //},
            "dynamic_templates": [
                {
                    "string_fields": {
                        "match": "*",
                        "match_mapping_type": "string",
                        "mapping": {
                            "type": "string",
                            "analyzer": "custom_whitespace"
                        }
                    }
                }
            ]
        }
    }
}

"custom_whitespace" , ​​ "keystone_service_list".
