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

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:

Sqoop 1.99.3 revision 2404393160301df16a94716a3034e31b03e27b0b

server version:

Sqoop 1.99.3 revision 2404393160301df16a94716a3034e31b03e27b0b

Protocol version:

\[1\]

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

Schema name: zhaobiao

Table name: zhaobiao

Table SQL statement:

Table column names:

Partition column name:

Nulls in partition column:

Boundary query:

Output configuration

Storage type:

Output directory: /Data/zhaobiao

Loaders:

New job was successfully created with validation status FINE  and persistent id 1

sqoop:000> update job

Required argument --jid is missing.

sqoop:000> update job --jid 1

Updating job with id 1

Please update job metadata:

Name: ImportPatents

Database configuration

Schema name: zhaobiao

Table name: CMS\_NEWS\_0625

Table SQL statement:

Table column names:

Partition column name:

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
