elasticsearch - Elasticsearch -在elasticsearch.yml中未配置节点属性如果没有节点属性，您将无法控制分片分配

Question

在Kibana中设置索引冷/热阶段时，会出现以下错误:

No node attributes configured in elasticsearch.yml
You can't control shard allocation without node attributes.

Learn about shard allocation. https://www.elastic.co/guide/en/elasticsearch/reference/7.3/shards-allocation.html

我已在所有3个节点上将碎片分配配置(在上面的链接中详细介绍)添加到elasticsearch.yml，但仍然收到相同的错误。我想念什么？

#SHARD ALLOCATION

Answer 1

要定义节点属性，应添加如下设置:

node.attr.[some attribute]: value

喜欢

node.attr.box_type: hot

然后您可以更改索引设置，使其位于非常冷的热节点上:

PUT /logs_2016-12-26
{
  "settings": {
    "index.routing.allocation.require.box_type": "hot"
  }
}

box_type在这里是任意属性。
