sqoop-1.4.4安装配置

环境：redhat6.5 hadoop2.4.1

step1 下载sqoop-1.4.4压缩包 http://mirror.bit.edu.cn/apache/sqoop/1.4.4/sqoop-1.4.4.bin__hadoop-2.0.4-alpha.tar.gz

step2 解压到/opt/sqoop/目录

tar -zxvf sqoop-1.4.4.bin__hadoop-2.0.4-alpha.tar.gz -C /opt/sqoop/

为了简化配置过程中涉及到的路径名称，建立一个链接到刚刚解压的路径的软链接,然后进入到/opt/sqoop-1.4.4中

ln -s /opt/sqoop/sqoop-1.4.4.bin__hadoop-2.0.4-alpha /opt/sqoop-1.4.4
cd /opt/sqoop-1.4.4

step3 配置环境变量 :编辑/etc/profile文件，在结尾加入如下代码

export SQOOP_HOME=/opt/sqoop-1.4.4
export HADOOP_COMMON_HOME=/opt/hadoop-2.4.1
export HADOOP_MAPRED_HOME=/opt/hadoop-2.4.1

step4. 复制lib包：

 a. 复制/opt/sqoop-1.4.4/sqoop-1.4.4.jar 包至 hadoop的lib路径下，否则报错： Error: Could not find or load main class org.apache.sqoop.Sqoop

 b. 复制连接mysql的java驱动包（如果用的是其他数据库，下载对应的java包即可），至/opt/sqooop-1.4.4/lib 和 hadoop 的l ib 下，否则报错： ERROR sqoop.Sqoop: Got exception running Sqoop: java.lang.RuntimeException: Could not load db driver class: com.mysql.jdbc.Driver (驱动包在mysql官网可以下载)

step5 修改/opt/sqoop-1.4.4/bin/configure_sqoop文件，将有关hbase的判断或export全部注释

step6. 测试sqoop，执行如下命令,结果大概如下，内容太长，就不敲了

root@cup bin# cd /opt/sqoop-1.4.4/bin
root@cup bin# ./sqoop help
