大數據學習——sparkSql對接hive

1.   安裝mysql

2.   上傳、解壓、重命名

2.1.  上傳

在隨便一臺有hadoop環境的機器上上傳安裝文件

su - hadoop

rz –y

2.2.  解壓

解壓縮：apache-hive-1.0.1-bin.tar.gz

tar -zxvf apache-hive-1.0.1-bin.tar.gz

2.3.  重命名

mv apache-hive-1.0.1-bin hive

3.   修改環境變量

su – root

vi /etc/profile

添加內容：

export HIVE_HOME=/home/hadoop/hive export PATH=$PATH::$HIVE_HOME/bin

source /etc/profile

su - hadoop
