异常

Caused by: org.elasticsearch.ElasticsearchStatusException: Elasticsearch exception [type=cluster_block_exception, reason=blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];]
        at org.elasticsearch.rest.BytesRestResponse.errorFromXContent(BytesRestResponse.java:177)

原因

集群存储资源高水位异常，默认当磁盘空间大于95%时，就会禁止写入。

解决

1. 首先让es节点腾出足够的空间、

   删除磁盘数据 ; 扩容。

2. 执行恢复命令

PUT _settings
{
  "index": {
    "blocks": {
      "read_only_allow_delete": "false"
    }
  }
}

让es恢复到可写入状态。问题解决！
