2.2 Hive安裝部署

1.Hive安裝及配置

(1)把a(bǔ)pache-hive-1.2.1-bin.tar.gz上傳到linux的/opt/software目錄下

(2)解壓apache-hive-1.2.1-bin.tar.gz到/opt/module/目錄下面

[atguigu@hadoop102 software]$ tar -zxvf apache-hive-1.2.1-bin.tar.gz -C /opt/module/

(3)修改apache-hive-1.2.1-bin.tar.gz的名稱為hive

[atguigu@hadoop102 module]$ mv apache-hive-1.2.1-bin/ hive

(4)修改/opt/module/hive/conf目錄下的hive-env.sh.template名稱為hive-env.sh

[atguigu@hadoop102 conf]$ mv hive-env.sh.template hive-env.sh

(5)配置hive-env.sh文件

(a)配置HADOOP_HOME路徑

export HADOOP_HOME=/opt/module/hadoop-2.7.2

(b)配置HIVE_CONF_DIR路徑

export HIVE_CONF_DIR=/opt/module/hive/conf

2.Hadoop集群配置

(1)必須啟動(dòng)hdfs和yarn

[atguigu@hadoop102 hadoop-2.7.2]$ sbin/start-dfs.sh

[atguigu@hadoop103 hadoop-2.7.2]$ sbin/start-yarn.sh

(2)在HDFS上創(chuàng)建/tmp和/user/hive/warehouse兩個(gè)目錄并修改他們的同組權(quán)限可寫

[atguigu@hadoop102 hadoop-2.7.2]$ bin/hadoop fs -mkdir /tmp

[atguigu@hadoop102 hadoop-2.7.2]$ bin/hadoop fs -mkdir -p /user/hive/warehouse

[atguigu@hadoop102 hadoop-2.7.2]$ bin/hadoop fs -chmod g+w /tmp

[atguigu@hadoop102 hadoop-2.7.2]$ bin/hadoop fs -chmod g+w /user/hive/warehouse

3.Hive基本操作

(1)啟動(dòng)hive

[atguigu@hadoop102 hive]$ bin/hive

(2)查看數(shù)據(jù)庫

hive>?show databases;

(3)打開默認(rèn)數(shù)據(jù)庫

hive>?use default;

(4)顯示default數(shù)據(jù)庫中的表

hive>?show tables;

(5)創(chuàng)建一張表

hive> create table student(id int, name string);

(6)顯示數(shù)據(jù)庫中有幾張表

hive>?show tables;

(7)查看表的結(jié)構(gòu)

hive>?desc student;

(8)向表中插入數(shù)據(jù)

hive> insert into student values(1000,"ss");

(9)查詢表中數(shù)據(jù)

hive> select * from student;

(10)退出hive

hive> quit;
