hive的安装，一般不容易察觉的hdfs的配置问题导致hive安装的失败

在安装hive的过程中，一般需要的准备环境就是hadoop集群的正常启动，要装有mysql，zookeeper.

具体怎么安装配置我在这里不多说，安装教程网上有挺多的。

我这里说下我遇到的问题，首先从解压安装开始说起，解压安装完成后，配置环境变量，

这些都是一些常规步骤。

还有一些配置文件的

当我输入hive的时候

[hadoop@master conf]$ hive

这个是完整的错误信息！

这个时候问题来了，求助网上，博客论坛等等，下面是我求助的结果：

问题六：
Caused by: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

解决办法：

[hadoop@HadoopSlave1 hive-1.2.1]$ hive --service metastore &

我就试了下：结果

[hadoop@master conf]$ hive --service metastore &
[]
[hadoop@master conf]$ Starting Hive Metastore Server

恭喜你，问题没解决！

[hadoop@HadoopSlave1 hive-1.2.1]$

将hadoop中share/hadoop/yarn/lib路径下jline包换成hive中匹配的jar包

看看这个方法貌似能解决我的问题，试试看先！结果吓一跳啊

进入hive的lib目录里

结果发现两个jline都是一样的版本，也就是说没有像上面的那个问题貌似的一样。

这下麻烦了，再回到错误本身吧，问题从这里切入

从hdfs开始入手

结果嘛，一打开网页

这个能正常打开啊，查看进程也没问题啊！！！

hdfs哪有什么问题啊，难道真的我在做梦啊！！！

对，这仅仅是常规的验证你是否配置正确的方法，但是！！！！这不是绝对的

检查hadoop的配置文件

OK没问题！！

问题出来了，这里配错了改会hdfs就没事了，在重启集群。

再回到开始遇到的问题本身

分析造成问题的原因，

 1才是问题的核心

成功了启动hive!!!!!

总结：这表面上看是hdfs的配置不对的常规问题，但是在这个页面和进程都正常启动的情况下

一般人是不会认为hdfs是没有配置好的。我们真的要多跟有经验的人交流，打破常规，不过能没有配置正确hdfs的情况下能把测试页面打开的人也只有我这中奇葩屌丝叫菜鸟了！！！
