Question

我已经将一个节点添加到5的Cassandra集群中，并且新节点加入时没有任何错误。但是，如果我在同一节点上输入nodetool状态，则缺少该集群的2个节点：

cassandra@cassandra-n8:~$ nodetool status

nodetool gossipinfo显示所有6个节点：

到目前为止，我重新启动了节点，可以看到所有的握手都做得很好。但是nodetool状态仍然失败。我错过了什么吗？

在您的帖子中，有两个节点没有状态。

cassandra@cassandra-n8:~$ nodetool gossipinfo
/10.140.120.27
  X_11_PADDING:{"workload":"Cassandra","active":"true"}
  RACK:rack1
  RPC_ADDRESS:10.140.120.27
  LOAD:2.69146405E10
  SEVERITY:2.0100502967834473
  HOST_ID:2564094b-08ea-42c4-82b0-a8246bd3ebcf

  NET_VERSION:7
  SCHEMA:17b20010-00c2-3035-94d2-ed9448b4190a

此节点的状态为STAT。

/10.53.186.53
  X_11_PADDING:{"workload":"Cassandra","active":"true"}
  RACK:rack1

我会看看启动日志，看看发生了什么，以及是否可以独立访问任何其他节点。

Cassandra nodetool状态与gossipinfo的输出不同
