Question

我正在尝试使用sstableloader将数据流式传输到Cassandra数据库，该数据库实际上位于同一节点中。它曾经在我使用DSE 2.2时工作，但当我将其升级到DSE 4.5并在cassandra.yaml文件中进行了所有相关更改时，它停止工作，现在它抛出了这样的错误：

我甚至尝试在cassandra.yaml文件中为listen_address，broadcast_address和rpc_address指定节点的实际IP地址，但是会发生同样的错误。

请问有人可以帮忙吗？

按照Zanson的建议，值得查看cassandra / conf / logback.xml中指定的system.log。

就我而言，问题只是节点上的磁盘空间耗尽：

        Observable.just(1, 2, 3)
                .concatWith(
                        Observable.just(2, 4, 6)
                                .filter(value -> ((value % 2) != 0))
                                // report if empty
                )

SSTable加载程序流失败，给出了java.io.IOException：由peer重置连接
