Cassandra 卡桑德拉的节点退役

当我试图使一个活动节点退役时，我遇到了以下异常。手册中没有提到我需要停止进入此节点的数据。即使如此，仍为活动节点指定退役

有人能告诉我我是否做错了什么，或者这是卡桑德拉的错误吗

使用的Cassandra版本：2.0.3

你使用了哪个命令

nodetool停用

？是的。我使用了./nodetool停用。您是否试图一次停用多个节点？否。我一次停用一个节点。但是，您能告诉我为什么要尝试将一次停用多个节点与此关联吗？当您停用一个节点时，其关键范围将在其余节点之间分割并流化。在这段时间内，这些节点被标记为“此节点正在从另一个节点接收数据”，因为如果您解除其中任何一个正确的节点的工作，则该数据将丢失。出于某种原因，只有一个设备退役时，这种情况才会发生在您身上。是新群集还是最近添加了新节点？
