Hawkular：无法连接到 LocalHost 上的 Cassandra DB

Question

我想在 Windows7 中建立一个 Hawkular 服务器 - 不幸的是这个服务器与 Cassandra DB 一起工作 - 我安装了最新版本并且在 Hawkular 的启动过程中我得到以下错误：

14:57:20,102 ERROR [org.hawkular.alerts.bus.log] (Thread-195 (ActiveMQ-client-global-threads-205387390)) HAWKALERT210009: Error accesing to DefinitionsService. Description: [java.lang.RuntimeException: Cassandra session is null]

Cassandra DB 在线，我可以使用 Cassandra CQL Shell 连接到 localhost:9160 - 但不是 hawkular 服务器 - 我是不是忘记了什么？

Answer 1

从日志中可以看出，Hawkular 尝试使用的端口是 9042。确保在 cassandra.yaml

中进行了此设置

start_native_transport: true
native_transport_port: 9042

您使用的端口 (9160) 是 thrift 端口。

Answer 2

信息有限，只能摸黑摸索

然而你说你连接到本地主机：9160。在日志中它提到“127.0.0.1:9042”。
