1：安装好hive，准备启动的时候出现下面的错误（由于hive是基于Hadoop的，所以必须先将你的集群启动起来，我就是没有启动集群，直接启动hive导致的错误）：

 [root@master bin]# ./hive

2：启动你的集群，然后再启动你的hive再次尝试：

 [root@master bin]# start-dfs.sh
 Starting namenodes on [master]
 master: starting namenode, logging to /home/hadoop/soft/hadoop-2.6./logs/hadoop-root-namenode-master.out
 master: starting datanode, logging to /home/hadoop/soft/hadoop-2.6./logs/hadoop-root-datanode-master.out

 [root@master bin]# jps

3：启动完集群以后再次启动hive的时候依旧还报错，不过是新的错误，如下所示，解决方法见下篇：

 [root@master bin]# ls
 beeline  ext  hive  hive-config.sh  hiveserver2  metatool  schematool
 [root@master bin]# clear
 ls
 [root@master bin]# ls
 beeline  ext  hive  hive-config.sh  hiveserver2  metatool  schematool
 [root@master bin]# ./hive

停更......
