Centos7 安装hive

安装hive

配置hive

在hdfs中新建目录/user/hive/warehouse

首先启动hadoop任务

hdfs dfs -mkdir /tmp

hdfs dfs -mkdir /user

hdfs dfs -mkdir /user/hive

hdfs dfs -mkdir /user/hive/warehouse

给新建的文件夹增加权限！

hadoop fs -chmod g+w /tmp

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

将mysql的驱动jar包mysql-connector-java-5.1.39-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

并将之命名为：hive-site.xml

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

使用vi hive-site.xml

修改下列属性值（通过/指令寻找，如果第一个定位不正确，n寻找下一个）
