安装配置Hive

1、下载Hive tar并解压

wget http://archive.apache.org/dist/hive/hive-2.1.0/apache-hive-2.1.0-bin.tar.gz

tar -xzf apache-hive-2.1.0-bin.tar.gz

2、配置环境

vi /etc/profile

export HIVE_HOME=/home/edureka/apache-hive-2.1.0-bin
export PATH=$PATH:/home/edureka/apache-hive-2.1.0-bin/bin

source /etc/profile

3、查看Hive版本

hive --version

4、在HDFS上创建Hive目录

hdfs dfs -mkdir -p /user/hive/warehouse

hdfs dfs -mkdir /tmp

5、为表设置读写权限

hdfs dfs -chmod g+w /user/hive/warehouse

hdfs dfs -chmod g+w /tmp

6、在hive-env.sh文件中设置hadoop路径

cd apache-hive-2.1.0-bin/

vi conf/hive-env.sh

export HADOOP_HOME=/usr/local/hadoop
export HADOOP_HEAPSIZE=512
export HIVE_CONF_DIR=/usr/local/hive/conf

7、编辑 hive-site.xml

vi conf/hive-site.xml

8、初始化Derby数据库，Hive默认数据库

bin/schematool -initSchema -dbType derby

9、登录Hive

10、运行几个语句

show databases;

create table employee (id string, name string, dept string) row format delimited fields terminated by ‘	’ stored as textfile;

LOAD DATA LOCAL INPATH '/srv/ftp/employee.txt' OVERWRITE INTO TABLE employee;

select * from employee;

11、退出Hive
