apache-hive-2.0.0安装

安装hive

安装在hadoop的namenode上，拷贝安装文件到linux中/usr/tools/apache-hive-2.0.0-bin.tar.gz

解压：

tar –zxvf apache-hive-2.0.0-bin.tar.gz

添加到环境变量

vi /etc/profile

编辑

exportHIVE_HOME=/usr/tools/apache-hive-2.0.0-bin

export PATH=$PATH:$HIVE_HOME/bin

保存后使其生效：

source /etc/profile

 

安装mysql作为hive的Metastore（已经安装了，可以跳过）

 

mysql默认不可以远程访问，设置远程访问

--GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;

上面这句远程访问不需要密码，如果需要密码使用下面这句

GRANT ALLPRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;

 

使权限生效：

FLUSH PRIVILEGES;

 

设置etc/my.cnf文件，使binlog_format=mixed

vi etc/my.cnf

将注释掉的binlog_format=mixed这一行前面的注释去掉然后保存，重启mysql即可

service mysql  restart

配置hive

在hdfs中新建目录/user/hive/warehouse

hdfs dfs –mkdir /tmp

hdfs dfs –mkdir /user

hdfs dfs –mkdir /user/hive

hdfs dfs –mkdir /user/hive/warehouse

 

hadoop fs -chmod g+w /tmp

hadoop fs -chmod g+w /user/hive/warehouse

将mysql的驱动jar包mysql-connector-java-5.1.7-bin.jar拷入hive的lib目录下面

进入hive的conf目录下面复制一下hive-default.xml.template名子命名为：hive-site.xml

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

使用schematool 初始化metastore的schema：

Schematool -initSchema -dbType mysql

 

运行hive（必须保证hadoop集群和mysql都已经启动）

hive
