当使用ElasticSearch原型2.1.0版本，结合Apache Storm 2.2.0版本和OpenJDK 11运行StormCrawler时，我在运行默认拓扑时遇到以下错误：
10:51:54.160 [main-SendThread(localhost:2000)] WARN o.a.s.s.o.a.z.ClientCnxn - Session 0x0 for server localhost/<unresolved>:2000, unexpected error, closing socket connection and attempting reconnect

这意味着什么？如何纠正？
刚刚发现这是对延迟回复的抱歉，但只是为了防止其他人有这个问题
根据Apache Storm本地集群"；无法规范化地址"；，这可以通过使用Storm 2.1.0 来修复
