sqoop的安装部署
1、下载sqoop-1.4.6.tar.gz和sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz
2、上传到/tools目录下
3、 解压
（1）tar -zvxf sqoop-1.4.6.tar.gz -C /training/
（2）配置环境变量：
export SQOOP_HOME=/training/sqoop-1.4.6
export PATH=$PATH:$PATH:SQOOP_HOME/bin
（3）让环境变量生效：source ~/.bash_profile
（4）进入到/training/sqoop-1.4.6/conf/目录下
cp sqoop-env-template.sh sqoop-env.sh
vi sqoop-env.sh
修改对应的选项：
#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/training/hadoop-2.7.3

                #Set path to where hadoop-*-core.jar is available
                export HADOOP_MAPRED_HOMEi=/training/hadoop-2.7.3

                #set the path to where bin/hbase is available
                #export HBASE_HOME=/training/hbase-1.3.1

                #Set the path to where bin/hive is available
                #export HIVE_HOME=/training/hive

                #Set the path for where zookeper config dir is
                export ZOOCFGDIR=/training/zookeeper-3.4.5

        （5）将mysql的驱动程序mysql-connector-java-5.1.44-bin.jar上传到/training/sqoop/lib目录下

        （6）进入到/tools目录下,解压sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz
                tar -zvxf sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz
                cd /tools/sqoop-1.4.6.bin__hadoop-2.0.4-alpha
                将sqoop-1.4.6.jar复制到/training/sqoop-1.4.6/lib/目录下（如果没有一步，会报错: 找不到或无法加载主类 org.apache.sqoop.Sqoop）
                cp sqoop-1.4.6.jar /training/sqoop-1.4.6/lib/
    4）、测试sqoop命令
            sqoop help
            不报错，即安装正确
