Question

尝试使用嵌入在AWS CDH4群集上的发现服务器运行Presto协调器服务器

config.properties：

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，它无法使用发现（相关日志）注册自己：

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

试图运行独立的Discovery服务器，效果相同。看起来在注册尝试后启动了监听器。

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。出现错误是因为发现客户端在发现服务器就绪之前启动。你会在日志中看到“成功刷新”，这表明它正在运行。我们最终会修复日志消息，但这纯粹是一个整容问题。
