第一步：进入客户端Shell
fulong@FBI008:~$ sqoop.sh client
Sqoop home directory: /home/fulong/Sqoop/sqoop-1.99.3-bin-hadoop200
Sqoop Shell: Type ‘help‘ or ‘\h‘ for help.
sqoop:000> set server --host FBI003 --port 12000 --webapp sqoop
Server is set successfully
sqoop:000> show version --all
client version:

第二步：创建连接
sqoop:000> create connection --cid 001
Creating connection for connector with id 1
Please fill following values to create new connection object
Name: 147patents
Connection configuration
JDBC Driver Class: oracle.jdbc.driver.OracleDriver
JDBC Connection String: jdbc:oracle:thin:@192.168.0.147:1521:ORCLGBK
Username: zhaobiao
Password: ******
JDBC Connection Properties:
There are currently 0 values in the map:
entry#
Security related configuration options
Max connections: 100
New connection was successfully created with validation status FINE and persistent id 1
第三步：创建Job
我这里顺便尝试了一下update命令，所以第一遍创建job时输入了错误的tablename：
sqoop:000> create job
Required argument --xid is missing.
sqoop:000> create job --xid 1 --type import
Creating job for connection with id 1
Please fill following values to create new job object
Name: ImportPatents
Database configuration

sqoop:000> update job

sqoop:000> update job --jid 1

Job was successfully updated with status FINE
总结：
1.create job时必须指定一个连接id
2.create job完成后，自动分配了一个job id
3.update job时，需要指定job id
4.创建Job过程中指定的Output directory指定的是HDFS中的路径
第四步：执行job
sqoop:000> start job --jid 1
2014-06-27 12:44:17 CST: FAILURE_ON_SUBMIT
Exception: org.apache.hadoop.mapred.FileAlreadyExistsException: Output directory hdfs://fulonghadoop/Data/zhaobiao already exists
