Hive初始化报错Exception in thread “main“ java.lang.NoSuchMethodError: com.google.common.base.

在进行Hadoop系列配置时真的踩了很多坑。

这篇时在Hive初始化：

bin/schematool -dbType derby -initSchema

报错：

这是因为hadoop和hive的两个guava.jar版本不一致，解决方案：
第一步：删除hive里的guava.jar
这个保存在hive的lib里，比如我的就在这个目录里面：

/root/apache-hive-3.1.2-bin/lib/

再用指令rm，删除

[root@master apache-hive-3.1.2-bin]# cd lib
[root@master lib]# rm guava-19.0.jar 
rm: remove regular file ‘guava-19.0.jar’? y
[root@master lib]# ls

第二步：把hadoop里的复制到hive里
我是先进入到hadoop的lib，再用cp指令复制到hive
(cp -r {要复制的文件} {指定复制过去的路径})

[root@master ~]# cd hadoop-3.2.2/share/hadoop/common/lib
[root@master lib]# cp -r guava-27.0-jre.jar /root/apache-hive-3.1.2-bin/lib

最后再回到hive, 再次初始化，终于成功了呜呜呜

[root@master hadoop]# cd /root/apache-hive-3.1.2-bin
[root@master apache-hive-3.1.2-bin]# bin/schematool -dbType derby -initSchema

因为没有直接找到详细的解决方案，折腾很久才解决，故在此做一个记录。
