我在cassandra和elastic search上有一个janusgraph集群。我使用spring（如果它很重要的话）和cassandra驱动程序版本3.6.0。但是我不能用数据填充服务器。有一个错误：

我在cassandra中手动安装了keyspace和table。但错误并没有消失。如何修复此错误？

这个错误的重要一点是 NoHostAvailableException :

Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException: \
  All host(s) tried for query failed ( \
    tried: cassandra.xxx.xxxx.xx/xx.x.xx.xxx:9042 ( \
      com.datastax.driver.core.exceptions.DriverException: \
      Error preparing query, got ERROR INVALID: unconfigured table systemlog \
    ) \
  )

司机抛出一个 NoHostAvailableException 在它尝试了查询计划中的每一个主机并用完了要尝试的主机之后。这可能是您得到“未配置表”的原因的线索。
当一个查询被发送到一个没有收到模式更改的节点时，该节点返回 unconfigured table <table_name . 最可能的原因是您有一个需要首先解决的模式分歧。
如果节点在进行架构更改时没有响应，那么这些节点将不会收到架构更改，因此它们的架构版本将与集群的其他节点不同。解决这个问题的最简单方法是在有问题的节点上重新启动cassandra。干杯！
