啟動配置有ElasticSearch參數的java jar 應用是報：
org.springframework.data.elasticsearch.ElasticsearchException: Bulk indexing has failures
ES新節點的數據目錄data存儲空間不足
1.提供足夠的存儲空間供數據寫入，如需在配置文件中更改ES數據存儲目錄，注意重啟ES
2.放開索引只讀設置，在Kibana的開發工具Dev Tools中執行
PUT _settings
{
"index.blocks.read_only_allow_delete": null
}
返回如下：
{
"acknowledged":true
}
--------------------------------
failed to load elasticsearch nodes : org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];
解決辦法：
curl -XPUT -H "Content-Type: application/json" http://master:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'
