Hive      https://www.cnblogs.com/xibuhaohao/p/11772481.html

一、下载sqoop

sqoop-1.4.7.tar 

http://mirror.bit.edu.cn/apache/sqoop/1.4.7/

二、安装sqoop

1、解压缩sqoop

tar -vzxf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz -C /home/hadoop/

 

2、sqoop文件目录重命名 

mv sqoop-1.4.7.bin__hadoop-2.6.0 sqoop-1.4.7.bin

3、配置sqoop环境变量

export SQOOP_HOME=/home/hadoop/sqoop-1.4.7.bin
export PATH=$PATH:$JAVA_HOME/bin:$SQOOP_HOME/bin

三、安装配置sqoop

1、配置sqoop配置文件

cd /home/hadoop/sqoop-1.4.7.bin/conf

cp sqoop-env-template.sh sqoop-env.sh

cat sqoop-env.sh

#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/home/hadoop/hadoop-2.8.5

#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/home/hadoop/hadoop-2.8.5

#set the path to where bin/hbase is available
#export HBASE_HOME=

#Set the path to where bin/hive is available
export HIVE_HOME=/home/hadoop/apache-hive-2.3.6-bin

#Set the path for where zookeper config dir is
#export ZOOCFGDIR=

2、验证安装配置

 

四、sqoop测试

1、MySQL测试
