启动hive报的错CliDriver.getCommandCompletor(CliDriver.java:530)
我一名coder，最新刚刚学习hive。在网上找了一个安装hive的文章，但是安装完之后启动hive 总是报一个错误（这个错误我解决了一周 nnd 太笨 shit ）今天我终于把他给搞定了，还是请教了一位网上的友人。非常感谢他给提供的思路。下面是错误的信息和解决方法。

错误如上，其实解决这个问题比较简单就是把jdk下jre/lib/endorsed/xercesImpl.jar和xml-apis.jar这两个文件给删除就可以。原因就是jar包冲突造成的。其实用到hive 的其它版本也会报这样类似的错误，我就不把所有的错误都罗列了。希望遇到这个错误的同学用这个办法解决。
