Elasticsearch

Question

在 Kibana 中设置索引 cold/warm 阶段时，出现此错误：

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

我已将分片分配配置（在上面link中有详细说明）添加到所有3个节点上的elasticsearch.yml，但仍然出现相同的错误。我错过了什么？

#SHARD ALLOCATION

cluster.routing.allocation.node_concurrent_incoming_recoveries: 2

要定义节点属性，您应该添加如下设置：

node.attr.[some attribute]: value

喜欢

node.attr.box_type: hot

稍后您可以更改索引设置并使其位于非常冷热的节点上：

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

box_type 是这里的任意属性。

Elasticsearch - elasticsearch.yml 中未配置节点属性没有节点属性无法控制分片分配
