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

Error:

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

 

出錯原因：內存不足，ElasticSearch進入“只讀”模式，節點無法更改。

 

解決方法：使用Postman軟件，運行以下URL，取消節點的只讀模式。

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

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

Body: 

{
  "index.blocks.read_only_allow_delete": null
}
