Mac OS 安装 Hive

Mac OS 安装 Hive

一、环境说明

• 操作系统：macOS High Sierra 10.13.2
• hadoop版本：apache hadoop 2.6.0
• mysql版本：mysql 5.7.22

• hive版本：apache hive 1.2.2

  二、安装步骤

1. 在mysql数据库创建hive用户

    mysql> create user 'hive' identified by 'hive';

2. 将mysql的所有权限授权给hive用户

    mysql> grant all on *.* to 'hive'@'localhost' identified by 'hive';

3. 刷新mysql使1、2步骤生效

    mysql> flush privileges;

4. 输入sql语句查询hive用户是否存在

       mysql> select host,user,authentication_string from mysql.user;
        +-----------+---------------+-------------------------------------------+
        | host      | user          | authentication_string                     |
        +-----------+---------------+-------------------------------------------+
        | localhost | root          | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
        | localhost | mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE |
        | localhost | mysql.sys     | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE |
        | %         | hive          | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC |
        | localhost | hive          | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC |
        +-----------+---------------+-------------------------------------------+
        5 rows in set (0.00 sec)

5. 使用hive用户登录mysql

    wudejin:~ oldsix$ mysql -u hive -p
    Enter password: hive
    mysql> 

6. 创建hive数据库

    mysql> create database hive;

7. 查看是否创建成功

    mysql> show databases;
    +--------------------+
    | Database           |
    +--------------------+
    | information_schema |
    | feature_ai         |
    | hive               |
    | mysql              |
    | performance_schema |
    | sys                |
    +--------------------+
    6 rows in set (0.00 sec)

   至此，前期的准备工作已完成，接下来，我们进入hive的安装过程。

8. 下载hive安装包，并解压

apache-hive安装包下载点击这里

下载完成后，通过命令行解压：

tar -zxvf apache-hive-1.2.2-bin.tar.gz

解压完成之后，对解压出来的文件夹重命名：

mv apache-hive-1.2.2-bin hive1.2.2

删除没用的hive压缩包：

rm -rf apache-hive-1.2.2-bin.tar.gz

1. 修改hive配置

进入hive1.2.2目录下的bin目录下，修改hive-site.xml配置文件

bin目录下不存在hive-site.xml文件，我们需要先复制一份：

cp hive-default.xml.template hive-site.xml

打开hive-site.xml文件：(找到对应name配置项，修改对应的value属性值)

• 修改数据库连接驱动名：

    
        javax.jdo.option.ConnectionDriverName
        com.mysql.jdbc.Driver
        Driver class name for a JDBC metastore
    

• 修改数据库连接URL：

    
        javax.jdo.option.ConnectionURL
        jdbc:mysql://localhost:3306/hive?characterEncoding=UTF-8
        JDBC connect string for a JDBC metastore
    

• 修改数据库连接用户名：

     
        javax.jdo.option.ConnectionUserName
        hive
        Username to use against metastore database
    

• 修改数据库连接密码：

    
        javax.jdo.option.ConnectionPassword
        hive
        password to use against metastore database
    

• 修改hive数据目录（三处）：

    
        hive.querylog.location
        /Users/oldsix/MyApp/data/hive/iotmp
        Location of Hive run time structured log file
    
  
    
        hive.exec.local.scratchdir
        /Users/oldsix/MyApp/data/hive/iotmp
        Local scratch space for Hive jobs
    
  
    
        hive.downloaded.resources.dir
        /Users/oldsix/MyApp/data/hive/iotmp
        Temporary local directory for added resources in the remote file system.
    

注：所修改hive数据目录需提前创建好

1. 配置hive环境变量

   cd ~
   sudo vi .base_profile

设置HIVE_HOME,并添加到PATH

export HIVE_HOME=/Users/oldsix/MyApp/hive
export PATH=$PATH:$HIVE_HOME/bin

保存退出，并使环境变量生效

source .base_profile

1. 将对应数据库的驱动包放到hive目录下的lib目录下

下载mysql-connector-java-5.1.40.jar，并上传至hive的lib目录下

1. 进入hadoop安装目录，启动hadoop：

   /sbin/start-all.sh

2. 命令行输入 jps 命令，查看hadoop是否启动成功

3. 启动hive

进入hive的bin目录下，执行命令： ./hive

再执行show tables;、show databases;语句

若出现如下面所示，说明hive启动成功：

wudejin:~ oldsix$ hive
readlink: illegal option -- f
usage: readlink [-n] [file ...]

若出现ERROR，hive将启动失败，下面记录了自己在启动hive时遇到的错误以及解决方案：

• Found class jline.Terminal, but interface was expected：

        at org.apache.hadoop.util.RunJar.main(RunJar.java:212)

问题原因：

hadoop2.6.0目录中存在较低版本的jline jar包（share/hadoop/yarn/lib/jline-0.9.94.jar),与hive1.2.2的lib目录下的jline jar包版本不符

解决办法：

删除hadoop的share/hadoop/yarn/lib目录下的jline-0.9.94.jar jar包，

将hive的lib目录下的jline-2.12.jar jar包复制到hadoop的share/hadoop/yarn/lib目录下

重启hadoop，再执行hive启动命令
