hadoop - accumulo 无法加载平板电脑

Question

Accumulo 无法加载、删除或创建新表。我的默认用户是 root。 Master 和 tablet server 和 zookeeper 还活着。
早些时候我试图通过使用 accululo init 重新初始化 accumulo 来解决这个问题，但错误仍然存​​在。我在累积日志中遇到以下异常:

Got loadTablet message from unauthenticatable user: !SYSTEM

当尝试从 shell 创建表时，shell 异常是:

[impl.ThriftTransportPool] WARN : Thread "shell" stuck on IO to host1:9999 (0) for at least 120061 ms  

Accumulo 仪表板日志是:
线程“tracer”在到 host1:9999 (0) 的 IO 上停留至少 120062 毫秒

检查您的配置。日志信息表明内部系统用户执行操作有问题。内部系统用户使用从配置中派生的凭据(例如 instance.secret 字段)。确保您的配置在集群中的所有节点上都是相同的。
