前提在hadoop、hive、Zookeeper、hbase搭建好的环境下进行
修改配置文件
在sqoop根目录下的conf目录中。
1) 重命名配置文件
$ mv sqoop-env-template.sh sqoop-env.sh
2) 修改配置文件
sqoop-env.sh
export HADOOP_COMMON_HOME=/opt/module/hadoop
export HADOOP_MAPRED_HOME=/opt/module/hadoop
export HIVE_HOME=/opt/module/hive
export ZOOKEEPER_HOME=/opt/module/zookeeper
export ZOOCFGDIR=/opt/module/zookeeper
export HBASE_HOME=/opt/module/hbase
3.3 拷贝JDBC驱动
拷贝jdbc驱动到sqoop的lib目录下，如：
$ cp mysql-connector-java-5.1.27-bin.jar /opt/module/sqoop-1.4.6.bin__hadoop-2.0.4-alpha/lib/
3.4 验证Sqoop
#通过某一个command来验证sqoop配置是否正确：
$ bin/sqoop help
出现一些Warning警告，并伴随着帮助命令的输出：
Available commands:
codegen Generate code to interact with database records
create-hive-table Import a table definition into Hive
eval Evaluate a SQL statement and display the results
export Export an HDFS directory to a database table
help List available commands
import Import a table from a database to HDFS
import-all-tables Import tables from a database to HDFS
import-mainframe Import datasets from a mainframe server to HDFS
job Work with saved jobs
list-databases List available databases on a server
list-tables List available tables in a database
merge Merge results of incremental imports
metastore Run a standalone Sqoop metastore
version Display version information
测试Sqoop是否能够成功连接数据库
$ bin/sqoop list-databases --connect jdbc:mysql://hadoop102:3306/ --username root --password passwd
#出现如下输出：
information_schema
metastore
mysql
oozie
performance_schema
