Question

我有一个测试设置，如果其中一个Cassandra节点关闭，sstableloader无法上传数据。我可以看到

有没有办法指示sstableloader不要连接（或打开流）到死节点（我不想从集群中解除/删除节点）？

Cassandra集群信息：Datastax社区版本2.1.2,3节点集群，其中2个是种子节点。

在测试批量上传期间，其中一个种子节点已关闭。密钥空间具有复制因子= 2。

遇到异常：

我想我可以将一个忽略列表传递给sstableloader。通过在忽略列表中传递死节点，sstableloader在我的测试设置中成功运行。

如果节点关闭，sstableloader无法上传数据
