更改Elasticsearch中现有索引的设置和映射 [英] Change settings and mappings on existing index in Elasticsearch

问题描述

我想在Elasticsearch中已经存在的索引上设置以下设置和映射：

I would like the following settings and mapping set on an already existing index in Elasticsearch:

{
    "analysis": {
        "analyzer": {
            "dot-analyzer": {
                "type": "custom",
                "tokenizer": "dot-tokenizer"
            }
        },
        "tokenizer": {
            "dot-tokenizer": {
                "type": "path_hierarchy",
                "delimiter": "."
            }
        }
    }
}

{
    "doc": {
        "properties": {
            "location": {
                "type": "string",
                "index_analyzer": "dot-analyzer",
                "search_analyzer": "keyword"
            }
        }
    }
}

我尝试添加这两行的代码：

I have tried to add these two lines of code:

client.admin().indices().prepareUpdateSettings(Index).setSettings(settings).execute().actionGet();
client.admin().indices().preparePutMapping(Index).setType(Type).setSource(mapping).execute().actionGet();

但这是结果：

org.elasticsearch.index.mapper.MapperParsingException: Analyzer [dot-analyzer] not found for field [location]

任何人？非常感谢，

：

if (client.admin().indices().prepareExists(Index).execute().actionGet().exists()) {            
    client.admin().indices().prepareClose(Index).execute().actionGet();
    client.admin().indices().prepareUpdateSettings(Index).setSettings(settings.string()).execute().actionGet();
    client.admin().indices().prepareOpen(Index).execute().actionGet();
    client.admin().indices().prepareDeleteMapping(Index).setType(Type).execute().actionGet();
    client.admin().indices().preparePutMapping(Index).setType(Type).setSource(mapping).execute().actionGet();
} else {
    client.admin().indices().prepareCreate(Index).addMapping(Type, mapping).setSettings(settings).execute().actionGet();
}

推荐答案

如果你看看你的设置发送更改后，您会注意到分析仪不在那里。实际上，您无法更改活动索引上的设置的分析部分。更好地用所需的设置创建它，否则你可以关闭它：

If you look at your settings after sending the changes you'll notice that the analyzer is not there. In fact you can't change the analysis section of the settings on a live index. Better to create it with the desired settings, otherwise you can just close it:

curl -XPOST localhost:9200/index_name/_close

当索引关闭时，您可以发送新设置。之后，您可以重新打开索引：

While the index is closed you can send the new settings. After that you can reopen the index:

curl -XPOST localhost:9200/index_name/_open

索引关闭时不使用任何集群资源，但不可读写。如果要使用Java API关闭并重新打开索引，可以使用以下代码：

While the index is closed it doesn't use any cluster resource, but it is not readable nor writable. If you want to close and reopen the index using the Java API you can use the following code:

client.admin().indices().prepareClose(indexName).execute().actionGet();
//TODO update settings
client.admin().indices().prepareOpen(indexName).execute().actionGet();
