一、没有mysql包

二、没有Hive文档

下载地址：hive word

三、hive初始化报错（ZLjava/lang/String;Ljava/lang/Object）

1、ZLjava/lang/String;Ljava/lang/Object

【bigdata@master hive】$ bin/schematool -dbType derby -initSchema
Exception in thread main java.lang.NoSuchMethodError: com.google.common.base.
Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;)V

2、原因hadoop和hive的两个guava.jar版本不一致

删除低版本的那个，将高版本的复制到低版本目录下

【bigdata@master hive】$ mv /opt/module/hive-3.1.2/lib/guava-19.0.jar /opt/module/hive-3.1.2/lib/guava-19.0.bak
【bigdata@master hive】$ cp /opt/module/hadoop-3.1.3/share/hadoop/common/lib/guava-27.0-jre.jar /opt/module/hive-3.1.2/lib/guava-27.0-jre.jar

四、修改Hive默认的数据库报的错

1、错误提示

一直默认的还是 jdbc:derby、没有走自己的配置的mysql

2、产生的问题

1 不是在atguigu账户

2最重要的还是 hive.size.xml （粘贴复制得分问题）

3、使用我手打 hive.size.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

    <property>
