[Sqoop]Sqoop安装

1. 下载

http://www.apache.org/dyn/closer.lua/sqoop/1.4.6

2. 解压

xiaosi@Qunar:~$ sudo tar -zxvf sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz -C /opt

进行重命名：

xiaosi@Qunar:/opt$ sudo mv sqoop-1.4.6.bin__hadoop-2.0.4-alpha sqoop-1.4.6

3. 配置环境变量

# sqoop
export SQOOP_HOME=/opt/sqoop-1.4.6
export PATH=${SQOOP_HOME}/bin:$PATH

4. 配置文件

xiaosi@Qunar:/opt/sqoop-1.4.6/conf$ sudo mv  sqoop-env-template.sh  sqoop-env.sh

进行如下修改：

# Set Hadoop-specific environment variables here.
#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/opt/hadoop-2.7.2
#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/opt/hadoop-2.7.2
#set the path to where bin/hbase is available
#export HBASE_HOME=
#Set the path to where bin/hive is available
export HIVE_HOME=/opt/apache-hive-2.0.0-bin
#Set the path for where zookeper config dir is
#export ZOOCFGDIR=/opt/zookeeper-3.4.8

如果数据读取不涉及hbase和hive，那么相关hbase和hive的配置可以不用配置；如果集群有独立的zookeeper集群，那么配置zookeeper，反之，不用配置。

5. Copy Jar包

所需的包：hadoop-core包、mysql的jdbc包（或Oracle的jdbc包等）

xiaosi@Qunar:~$ sudo mv hadoop-core-1.2.1.jar /opt/sqoop-1.4.6/lib/
xiaosi@Qunar:~$ sudo mv mysql-connector-java-5.1.38.jar /opt/sqoop-1.4.6/lib/

6. 测试验证

xiaosi@Qunar:/opt/sqoop-1.4.6/bin$ sqoop list-databases --connect jdbc:mysql://localhost:3306 --username root -password root
