使用 DSE 4.8.6 (C* 2.1.13.1218)
当我尝试在新数据中心添加新节点时，引导/节点重建总是被流错误中断。
system.log 中的错误示例：
ERROR [STREAM-IN-/172.31.47.213] 2016-04-19 12:30:28,531 StreamSession.java:621 - [Stream #743d44e0-060e-11e6-985c-c1820b05e9ae] Remote peer 172.31.47.213 failed stream session.

大约有 500GB 的数据要流式传输到新节点。Boostrap 或重建操作流来自另一个（主）DC 上的 4 个不同节点。
当发生流错误时，所有同步的数据都会被擦除（我必须重新开始）。
到目前为止我尝试了什么：
- 引导节点
- 设置
auto_boostrap: False并cassandra.yaml手动运行nodetool rebuild - 在我的 linux conf 中禁用
streaming_socket_timeout_in_ms和设置更积极的 TCP Keep Alive 值（遵循CASSANDRA-9440票证中的建议） - 增加
phi_convict_threshold（最大） - 不要引导节点并使用修复来流式传输数据（在几乎满的磁盘和 80K SSTables 处停止修复。尝试压缩它们 3 天后，我放弃了）
还有什么我应该尝试的吗？我正在nodetool scrub每个失败的节点上运行，看看这是否有帮助......
在流输出节点上，这些是错误消息：
