Today I troubleshooted an Elasticsearch-cluster-down issue. Several lessons were learned: When many elasticsearch cluster nodes are restarted, to avoid HEAP spike, better to temporarily stop all connection attempts; Avoid setting allow_primary=true w…

问题/现象: 业务信息流转的某些环节,会向相关人员发送通知邮件,邮件中附带有链接,供相关人员进入察看或处理业务.客户要求邮件中的链接,需要进行限制,只有特定人员才能进入处理或察看.总管想了想,应道没问题,不一会儿就改好了,在业务信息的查询方法中添加了限制——非处理人不得进入.测试这边,忙得脚不沾地,一人扛了两个项目的测试,但还是按照预先设计的测试用例,对该修改进行了测试,测试结果ok,非处理人通过邮件链接进入后,确实提示了“你没有权限,翻滚着离去吧”. 当晚发布生产后,客户一封邮件甩过来:管理员…
