这个必须记一笔：
今天在安装配置完hive后，进入了hive的命令行执行show databases时抛出一下错误：
FAILED: Error in metadata: MetaException(message:Got exception: java.net.ConnectException Call to hadoop0/192.168.0.10:9000 failed on connection exception: java.net.ConnectException: Connection refused)
后来经过查阅资料发现我忘记启动hadoop集群了！（真是无语了。。。）
重新执行start-all.sh启动hadoop集群！
然后进入hive命令行执行show databases;
hive> show databases
> ;
OK
default
Time taken: 7.488 seconds
结果已经出来了！
