本文详细记录了在使用ImpalaShell过程中遇到的未进行Kerberos认证导致的问题，以及HBase服务启动异常的错误日志。通过分析，总结了解决方案，包括解除集群的安全模式、检查hostname和hosts文件配置，以及处理两个nm节点同时处于slave状态的情况。

直接上干货，报错日志是这些：

下面我将说说网上提供的解决方案：

最多的解释：

集群处于安全模式：解决方法，解除安全模式

命令：hadoop dfsadmin -safemode get

hadoop dfsadmin -safemode leave

另一种解释：

hostname和hosts文件写错了，仔细检查，hosts和hostname文件看看是否有异常

而我今天遇到的问题是：

两个nm节点同时处于slave状态，具体原因不详，待我细查之后，回复本文。

解决方法重启master服务或者切换一个slave
