hive安装，

su - hadoop
xftp打开/home/hadoop/soft
上传

tar -xvf apache-hive-1.2.2-bin.tar.gz
mv apache-hive-1.2.2-bin …/install/hive

cd /home/hadoop/install/hive

修改环境变量
vim /etc/profile

export JAVA_HOME=/usr/local/jdk
export HADOOP_HOME=/home/hadoop/install/hadoop-2.7.4
export MYSQL_HOME=/usr/local/mysql
export HIVE_HOME=/home/hadoop/install/hive
export PS1="[\u@\h \w]$"
export PATH=$PATH:$JAVA_HOME/bin:$HADOO{P}_{H}OME\mathrm{/}bin:$HADOOP_HOME/sbin:$MYSQ{L}_{H}OME\mathrm{/}bin:$HIVE_HOME/bin

HIVE存放元数据（将HDFS文件，映射为HIVE里面的表结构定义信息—>元数据信息）
数据是存储在HDFS上的
但是元数据信息derby mysql

HIVE—>MYSQL需要JDBC的支持，我们需要把JDBC包拷贝到hive/lib目录下
cp /home/hadoop/soft/mysql-connector-java-5.1.38.jar /home/hadoop/install/hive/lib

MySQL赋权操作

create database hive default character set latin1;
grant all on . to ‘hive’@’%’ identified by ‘hive’;
flush privileges;

mysql> create database hive default character set latin1;
Query OK, 1 row affected (0.04 sec)

mysql> grant all on . to ‘hive’@’%’ identified by ‘hive’;
Query OK, 0 rows affected (0.04 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.03 sec)

mysql> select user,host,password from mysql.user;
±-----±----------±------------------------------------------+
