我正在尝试使用一些数据批量加载4节点Cassandra 3.0.10群集。我已经按照文档成功生成了SStables，但似乎我无法让sstableloader加载它们。
我收到以下 java.net.ConnectException：拒绝连接
bin/sstableloader -v -d localhost test-data/output/si_test/messages/

该实用程序似乎连接到群集（ ...已建立的与初始主机的连接.. ），但我不会流式传输数据。
到目前为止，我已尝试调试此问题：
删除目标键空间（并获得了不同的错误），通过cqlsh再次创建
我可以通过端口9042和7000远程登录到群集的每个节点
nodetool enablethrift 修改
这是netstat -an | grep 7000的输出。节点只有一个网络接口，Cassandra正在监听它。它还与端口7000上的所有其他节点建立了连接。

将初始主机从127.0.0.1更改为网络中节点的实际地址会导致 com.datastax.driver.core.exceptions.TransportException ：

答案 0 :(得分：4)
它试图连接到存储端口（7000）。它最有可能绑定到与127.0.0.1不同的接口。您可以使用netstat -an | grep 7000检查其绑定内容。您可能需要仔细检查任何防火墙或iptable设置。
UPDATE：未绑定到127.0.0.1，这是默认值，但是为172.31.3.88。所以请致电sstableloader -v -d 172.31.3.88 test-data/output/si_test/messages/
此外，如果您启用了ssl（cassandra.yaml中为server_encryption_options），则需要使用7001并将其配置为匹配。如果你可以telnet到7000，那很可能不是那样的。
值得注意的是，启用节俭不一定是3.0.10。 sstableloader不再使用它（在旧版本中，它用于读取模式）。
答案 1 :(得分：1)
解决了将 cassandra.yaml 文件中的 rpc_address 从默认的localhost更改为每个节点的实际地址。
