Question

在Windows 7中建立一个Hawkular Server - 不幸的是这个服务器与Cassandra DB一起使用 - 我安装了最新版本，在Hawkular的启动过程中我遇到了以下错误：

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

Answer 1

从日志中，Hawkular尝试使用的端口是9042.确保start_native_transport: true native_transport_port: 9042

中的此设置

ViewContainerRef.createComponent()

您正在使用的端口（9160）是节俭端口。

Answer 2

我只能用如此有限的信息在黑暗中刺伤。

但是你说你连接到localhost： 9160 。在日志中它提到“127.0.0.1:9042”。

Hawkular：无法连接到LocalHost上的Cassandra数据库
