hive环境部署

$ tar -zxvf apache-hive-2.1.1-bin.tar.gz 
$ mv apache-hive-2.1.1-bin.tar.gz hive-2.1.1 
配置环境变量(同上)

export HIVE_HOME=/home/ranrl/opt/hive-2.1.1 
export HIVE_CONF_DIR=$HIVE_HOME/conf 
export PATH=\$PATH:\$HIVE_HOME/bin

在hive的目录下，新建warehouse、tmp、log文件夹。 
修改配置文件，下面是hive的配置文件conf目录

-rw-r--r-- 1 ranrl root   1596 Nov 29 05:32 beeline-log4j2.properties.template
-rw-r--r-- 1 ranrl root 229198 Nov 30 03:46 hive-default.xml.template
-rw-r--r-- 1 ranrl root   2378 Nov 29 05:35 hive-env.sh.template
-rwxr-xr-x 1 ranrl root   2274 Feb  7 17:09 hive-exec-log4j2.properties
-rw-r--r-- 1 ranrl root   2274 Nov 29 05:32 hive-exec-log4j2.properties.template
-rw-r--r-- 1 ranrl root   2925 Nov 29 05:32 hive-log4j2.properties.template
-rw-r--r-- 1 ranrl root   2060 Nov 29 05:32 ivysettings.xml
-rw-r--r-- 1 ranrl root   2719 Nov 29 05:32 llap-cli-log4j2.properties.template
-rw-r--r-- 1 ranrl root   4353 Nov 29 05:35 llap-daemon-log4j2.properties.template
-rw-r--r-- 1 ranrl root   2662 Nov 29 05:32 parquet-logging.properties

$ cp hive-env.sh.template hive-env.sh 
$ cp hive-log4j2.properties.template hive-log4j2.properties 
$ cp hive-default.xml.template hive-site.xml

修改后配置文件如下：

-rw-r--r-- 1 ranrl root   1596 Nov 29 05:32 beeline-log4j2.properties.template
-rw-r--r-- 1 ranrl root 229198 Nov 30 03:46 hive-default.xml.template
-rwxr-xr-x 1 ranrl root   2440 Feb  7 17:31 hive-env.sh
-rw-r--r-- 1 ranrl root   2378 Nov 29 05:35 hive-env.sh.template
-rwxr-xr-x 1 ranrl root   2274 Feb  7 17:09 hive-exec-log4j2.properties
-rw-r--r-- 1 ranrl root   2274 Nov 29 05:32 hive-exec-log4j2.properties.template
-rwxr-xr-x 1 ranrl root   2925 Feb  7 17:09 hive-log4j2.properties
-rw-r--r-- 1 ranrl root   2925 Nov 29 05:32 hive-log4j2.properties.template
-rwxr-xr-x 1 ranrl root   2514 Feb  7 18:43 hive-site.xml
-rw-r--r-- 1 ranrl root   2060 Nov 29 05:32 ivysettings.xml
-rw-r--r-- 1 ranrl root   2719 Nov 29 05:32 llap-cli-log4j2.properties.template
-rw-r--r-- 1 ranrl root   4353 Nov 29 05:35 llap-daemon-log4j2.properties.template
-rw-r--r-- 1 ranrl root   2662 Nov 29 05:32 parquet-logging.properties修改hive-env.sh，去掉前面的注释#，加上相应的路径 

修改hive-env.sh，去掉前面的注释#，加上相应的路径 

export HADOOP_HEAPSIZE=1024 
HADOOP_HOME=/home/ranrl/opt/hadoop-2.7.3 
export HIVE_CONF_DIR=/home/ranrl/opt/hive-2.1.1/conf 
export HIVE_AUX_JARS_PATH=/home/ranrl/opt/hive-2.1.1/lib

这儿采用mysql作为hive的元数据库 
在自己的mysql中为hive新建一个用户：grant all privileges on . to ‘hive’ @ ‘%’ identified by ‘password’ 
修改hive-site.xml文件，添加相应的路径和mysql数据库，用户名，密码

    hive.metastore.warehouse.dir
    /home/ranrl/opt/hive-2.1.1/warehouse
    location of default database for the warehouse
 
 
    hive.querylog.location
    /home/ranrl/opt/hive-2.1.1/log
    Location of Hive run time structured log file
 
 
    hive.downloaded.resources.dir
    /home/ranrl/opt/hive-2.1.1/tmp
    Temporary local directory for added resources in the remote file system.
 
 
    javax.jdo.option.ConnectionURL
    jdbc:mysql://localhost:3306/hive
    
      JDBC connect string for a JDBC metastore.
      To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.
      For example, jdbc:postgresql://myhost/db?ssl=true for postgres database.
    
  
  
javax.jdo.option.ConnectionDriverName
    com.mysql.jdbc.Driver
    Driver class name for a JDBC metastore
  
 
    javax.jdo.option.ConnectionUserName
    hive
    Username to use against metastore database
  

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

5. 下载mysql-connector-java

地址：https://dev.mysql.com/downloads/connector/j/ 
解压得到mysql-connector-java-5.1.40.jar,拷贝到hive的lib目录下。

6. 在进入hive目录下的bin目录，运行命令：./schematool -initSchema -dbType mysql

现在hive已经安装成功，输入hive命令，即可运行hive

show databases; 
create database test; 
use test; 
hive> CREATE TABLE test(id int,name string) ROW FORMAT DELIMITED FIELDS TERMINATED BY ‘\t’; 
select * from test ；运行正常说明hive已经安装成功
