java - Cassandra sstableloader - 连接被拒绝

Question

我正在尝试使用一些数据批量加载一个 4 节点 Cassandra 3.0.10 集群。我已经按照文档成功生成了 SStables，但是似乎我无法让 sstableloader 加载它们。

我收到以下 java.net.ConnectException: Connection refused

bin/sstableloader -v -d localhost test-data/output/si_test/messages/

该实用程序似乎连接到集群(...已建立与初始主机的连接..)，但我没有流式传输数据。

到目前为止我为调试问题所做的尝试:

• 删除了目标键空间(并得到了不同的错误)，通过 cqlsh 重新创建

• 我可以通过端口 9042 和 7000 telnet 到集群的每个节点

• 使用 nodetool enablethrift 启用节俭

这是 netstat -an | 的输出grep 7000。这些节点只有一个网络接口(interface)，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:

这就是它尝试连接到存储端口 (7000) 的过程。它很可能绑定(bind)到与 127.0.0.1 不同的接口(interface)。您也可以使用 netstat -an | 检查它的绑定(bind)。 grep 7000。您可能需要仔细检查任何防火墙或 iptable 设置。

更新:它未绑定(bind)到默认的 127.0.0.1，而是绑定(bind)到 172.31.3.88。所以调用 sstableloader -v -d 172.31.3.88 test-data/output/si_test/messages/

此外，如果您启用了 ssl(cassandra.yaml 中的 server_encryption_options)，您需要使用 7001 并将其配置为匹配。如果您可以远程登录到 7000，则很可能不是这样。

值得注意的是，在 3.0.10 中不一定启用节俭。 sstableloader 不再使用它(在旧版本中它用于读取模式)。
