我在AWS上使用3個EC2實例節點的cassandra集羣。在ec2上使用ebs更改私有IP時，Cassandra2.0.1無法重新啓動
每個節點都將一個EBS卷掛載到路徑（/ usr/lib/cassandra /）中，因此cassandra的數據存儲在EBS卷中。
所有節點都有一個dns指向自己的私有ip。所有的cassandra配置文件都使用DNS而不是私有IP。
我的問題是：當一個節點被終結時，我將另一個cassandra拉開，並將EBS掛載到新啓動的實例，這樣數據就不會丟失。但是當啓動cassandra服務時，cassandra服務將失敗。日誌如下：
我不知道爲什麼它會使用其他節點的IP？
