elasticsearch - elasticdump 导入索引设置不起作用

Question

我可以使用下面的命令导出索引设置

elasticdump --input=http://localhost:9200/tempIndex --output=/Users/Desktop/indexFile --type=settings

但是当我尝试导入相同的设置时，它并没有更新索引设置

我用于导入的命令是:

elasticdump --input=/Users/Desktop/indexFile --output=http://localhost:9200/tempIndex --type=settings

命令输出:

 07:06:33 GMT | starting dump
 07:06:33 GMT | got 1 objects from source file (offset: 0)
 07:06:34 GMT | sent 1 objects to destination elasticsearch, wrote 0
 07:06:34 GMT | got 0 objects from source file (offset: 1)
 07:06:34 GMT | Total Writes: 0
 07:06:34 GMT | dump complete

下面是我使用 elasticdump settings 选项导出的索引设置

{
    "tempIndex":{
        "settings":{
            "index":{
                "mapping":{
                    "nested_fields":{
                        "limit":"2000"
                    },
                    "total_fields":{
                        "limit":"2000"
                    }
                },
                "analysis":{
                    "normalizer":{
                        "lowercase_normalizer":{
                            "filter":[
                                "lowercase"
                            ],
                            "type":"custom",
                            "char_filter":[

                            ]
                        }
                    }
                },
                "number_of_shards":"5",
                "number_of_replicas":"1"
            }
        }
    }
}

只能在创建索引时添加设置。所以运行这条命令时索引一定不能存在。您可以通过提供适当的 URL 来短路，但由于您正在尝试更新非动态设置，它仍然会失败。

{
    "error": {
        "root_cause": [{
            "type": "illegal_argument_exception",
            "reason": "Can't update non dynamic settings [[index.number_of_shards]] for open indices [[source_index/_OdHe-IVQBemJ3YYka_9hg]]"
        }],
        "type": "illegal_argument_exception",
        "reason": "Can't update non dynamic settings [[ index.number_of_shards]] for open indices [[source_index/_OdHe-IVQBemJ3YYka_9hg]]"
    },
    "status": 400
}

你可以做到

# passing in _settings path will change operation from insert to update
elasticdump --input=/Users/Desktop/indexFile --output=http://localhost:9200/tempIndex/_settings --type=settings
