HIve安装踩坑手册，简述java内存模型面试

四、错误记录

1、配置文件中存在异常字符

二、guava版本不一致

---

一、安装环境

======

JDK 1.8

二、安装Hadoop

==========

1、下载hadoop

http://mirror.bit.edu.cn/apache/hadoop/ 选择合适的版本

下载hadoop

wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-3.3.0/hadoop-3.3.0.tar.gz

执行 进行解压，为了方便使用吗，mv进行修改名称

tar -xzvf hadoop-3.3.0.tar.gz

mv hadoop-3.3.0.tar.gz  hadoop

2、修改环境变量

将hadoop环境信息写入环境变量中

vim /etc/profile

export HADOOP_HOME=/opt/hadoop

export PATH=$HADOO{P}_{H}OME/bin:$PATH

执行source etc/profile使其生效

3、修改配置文件

修改hadoop-env.sh文件，vim etc/hadoop/hadoop-env.sh修改JAVA_HOME信息

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.262.b10-0.el7_8.x86_64

执行hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-3.3.0.jar grep input output ‘dfs[a-z]’，hadoop自带的例子，验证hadoop是否安装成功

三、安装hive

========

1、下载hive

wget http://mirror.bit.edu.cn/apache/hive/hive-3.1.2/apache-hive-3.1.2-bin.tar.gz

解压tar -zxvf apache-hive-3.1.2-bin.tar.gz

修改名称 mv apache-hive-3.1.2-bin hive

2、修改环境变量

vim /etc/profile

export HIVE_HOME=/opt/hive

export PATH=$MAVE{N}_{H}OME/bin:$HIVE_HOME/bin:$HADOO{P}_{H}OME/bin:$PATH

source etc/profile

3、修改hivesite 配置

javax.jdo.option.ConnectionUserName用户名

root

javax.jdo.option.ConnectionPassword密码

123456

javax.jdo.option.ConnectionURLmysql

jdbc:mysql: //127.0.0.1:3306/hive

javax.jdo.option.ConnectionDriverNamemysql驱动程序

com.mysql.jdbc.Driver

hive.exec.script.wrapper

复制mysql的驱动程序到hive/lib下面，然后进入/hive/bin 目录执行

schematool -dbType mysql -initSchema

4、验证是否安装成功

hive --version查看当前版本

hive 看是否进入hive命令操作行，进去的话说明成功

四、错误记录

======

1、配置文件中存在异常字符

根据指定的
