根据kudu的官方文档，我已经成功地在ubuntu（trusty）上安装了kudu（参见http://kudu.apache.org/docs/installation.html ). 安装程序有一个节点运行master和tablet server，另一个节点仅运行tablet server。我在运行kudu master的节点上安装没有cloudera管理器的impala kudu时遇到问题。我已经按照cdh的安装说明进行了操作（参见http://www.cloudera.com/documentation/enterprise/latest/topics/cdh_ig_cdh5_install.html )翻到第3步。我避免了用yarn和mrv1安装cdh，因为我不需要运行任何mapreduce作业，也不会使用hadoop。impala kudu和impala kudu外壳安装无误。当我启动 Impala 外壳时，它返回：

Starting Impala Shell without Kerberos authentication

我尝试使用connect选项连接到kudu主节点，但没有成功。imapala kudu和kudu都在同一台机器上运行。是否有需要更改的其他配置设置，或者hadoop和yarn是使impala kudu工作的严格要求？
运行后 ps -ef | grep -i impalad 我可以确认 Impala 守护进程没有运行。在导航到impala日志~/var/log/impala之后，我发现了一些错误和警告文件。以下是impalad.error的输出：

也许我需要重新访问hdfs和hivemetastore以确保这些服务配置正确？
