elasticsearch客户端，用于Java中的弹性搜索

Question

我正在尝试为弹性搜索编写一个插件，它将对弹性搜索执行一个简单的查询并检索结果。这是我的错误。有人能帮我吗

This  is the error :
{"error":"BindTransportException[Failed to bind to [9300-9400]]; nested: IllegalStateException[await*() in I/O thread causes a dead lock or sudden performance drop. Use addListener() instead or call await*() from a different thread.]; ","status":
