Question

我有一个15节点的cassandra 3.9集群。我最近遇到了一个问题，其中一个节点堆积了GossipStage消息。根据我在类似报告中找到的一些指导，我在该节点上运行了“nodetool resetlocalschema”。虽然像这样的八卦错误继续显示在日志中

WARN  [GossipTasks:1] 2018-02-11 23:55:34,197 Gossiper.java:771 - Gossip stage has 180317 pending tasks; skipping status check (no nodes will be marked down)

我也看到以下异常。有关如何克服此问题并使此节点恢复正常的任何指导？另外我应该提一下我在cassandra.yaml文件中启用了PasswordAuthenticator。

实际上，只需先重新启动群集的种子节点，然后重新启动群集中的其余节点，即可解决此问题。感谢所有的投入。真的很感激。

运行nodetool resetlocalschema会导致异常抱怨system_auth密钥空间不存在
