解决Elasticsearch的[FORBIDDEN/12/index read-only / allow delete (api)];]问题

Error:

ElasticsearchException[Elasticsearch exception [type=cluster_block_exception, reason=blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];]]

 

出错原因：内存不足，ElasticSearch进入“只读”模式，节点无法更改。

 

解决方法：使用Postman软件，运行以下URL，取消节点的只读模式。

PUT         http://127.0.0.1:9200/_all/_settings

Headers:   KEY = Content-Type, VALUE = application/json

Body: 

{
  "index.blocks.read_only_allow_delete": null
}
