hive语句分区归档时报错：java.lang.NoClassDefFoundError: org/apache/hadoop/tools/HadoopArchives

一、报错信息：

在我执行分区归档时命令：alter table hive_text archive partition (folder='docs');

报错如下：

查看日志：cat /tem/hive/root/hive.log(这是我的日志路径),报错日志如下

默认日志路径：/tmp/<user.name>文件夹的hive.log文件中，全路径就是/tmp/当前用户名(root)/hive.log。

二、解决方法

将/usr/local/hadoop-2.7.1/share/hadoop/tools/lib(你自己hadoop的目录,此目录我的hadoop安装目录)下的

hadoop-archives-2.7.6.jar包放入  /usr/local/hive122/lib(根据自己的安装目录)目录下

扩展：其实诸如此类问题，大部分都是应为少了jar包,去相应的目录找到所需要的jar包放到对应的目录下即可解决问题。

再次执行成功！！！！
