我有Cassandra v3.9,3节点集群。复制因子2
10.0.0.11,10.0.0.12,10.0.0.13
10.0.0.11,10.0.0.12是种子节点
在/etc/cassandra/conf/debug.log中出现以下错误的可能原因
错误是
DEBUG [RMI TCP连接（174）-127.0.0.1] 2017-07-12 04：47：49,002 StorageProxy.java:2254 - 主机不同意。没有得到每个人的回复：10.0.0.13
UPDATE1：
在出现错误时，这里有来自所有服务器的一些统计信息

上述错误发生在10.0.0.11的/var/log/cassandra/debug.log中
10.0.0.13上/var/log/cassandra/debug.php中的错误
