尝试在 AWS CDH4 集群上嵌入发现服务器的 Presto 协调器服务器

配置属性：

coordinator=true
datasources=jmx
http-server.http.port=8000
presto-metastore.db.type=h2
presto-metastore.db.filename=var/db/MetaStore
task.max-memory=1GB
discovery-server.enabled=true
discovery.uri=http://ip-10-0-0-11:8000

当服务器启动时，它无法注册自己的发现（相关日志）：

2013-11-08T19:38:38.193+0000     WARN   main    Bootstrap   Warning: Configuration property 'discovery.uri' is deprecated and should not be used

尝试也运行独立的发现服务器，同样的效果。看起来在注册尝试后启动了侦听器。

我想知道是否有人会在日志中注意到这一点:) 这实际上不是问题。出现该错误是因为发现客户端在发现服务器准备好之前启动。不久之后，您会在日志中看到“刷新成功”，这表明它正在工作。我们最终会修复日志消息，但这纯粹是一个表面问题。
