Question

我正在尝试连接到远程服务器但获得以下异常.... 不知何故，似乎cassandra无法连接到每个节点...

user$ sstableloader -d 192.168.33.11  /usr/local/var/lib/cassandra/data/moomin/hoahoa2/

[1]通过cqlsh，我可以顺利连接到任一节点。

[2]每个节点中的cassandra.yaml文件都有rpc_address：0.0.0.0

有人可以给我建议吗？

Answer 1

好吧，我终于明白了，每个节点的cassandra版本都不相同，这会导致java.net.ConnectionException错误。所以我要做的就是确保每个节点的cassandra版本相同。

如果cassandra版本相同，则java版本不必相同。

sstableloader连接拒绝，但可以通过cqlsh连接
