Sqoop import\connect JDBC:Mysql://mysql.example.com/sqoop\username sqoop\password sqoop\table regions\compress

To change compression format:

Sqoop import –cmpress\--compress-codec org.apache.hadoop.io.compress.BZip2Codec

Sqoop import\--connect jdbc:mysql://mysql.example.com/sqoop\--username sqoop\--password sqoop\table regions\incremental append\--check-column id\--last-value20

Sqoop import\--connect jdbc:mysql://mysql.example.com/sqoop\--username sqoop\--password sqoop\table regions\incremental lastmodified\--check-column last_update_date\--last-value “2018-06-11 00:01:01”

Sqoop import\--connect jdbc:mysql://mysql.example.com/sqoop\ username sqoop\password sqoop\table regions

Directories: -target-dir and –warehouse-dir.

-target-dir option imports the real data to the specified directory. Above listed two commands can be used in the following ways:

Sqoop import \ connect JDBC:Mysql://mysql.example.com/sqoop\usernae sqoop\password sqoop\ table regions\target-dir/etc/input/cities

-warehouse-dir option creates a table name directory and data is imported in that directory, like shown below:

Sqoop import\-connect JDBC:Mysql://mysql.example.com/sqoop\username sqoop\password sqoop\table regions\warehouse-dir/etl/input/

Sqoop import\connect JDBC:Mysql://mysql.example.com/sqoop\username sqoop\password sqoop\table regions\ where “country=’USA’ ”

Sqoop import\connect JDBC: Mysql://mysql.example.com/sqoop\username sqoop\table regions\ -P

To read a password from a file:

Sqoop import\connect JDBC:Mysql://mysql.example.com/sqoop\username sqoop\password sqoop\table regions\ password-file my-sqoop-password

Sqoop import\connect JDBC:Mysql://mysql.example.com/sqoop\username sqoop\password sqoop\table regions\as-sequence file

Sqoop import-all-tables\--connect JDBC:Mysql://mysql.example.com/sqoop\--username sqoop\password sqoop\table cities\

OR

Sqoop import-all-tables\--connect JDBC:Mysql://mysql.example.com/sqoop\--username sqoop\--password sqoop\table cities\ --exclude-tables cities,countries

Sqoop export\--connect JDBC:Mysql://mysql.example.com/sqoop\--username sqoop\--password sqoop\--table regions\ --export-dir regions

Sqoop export\--connect JDBC:Mysql://mysql.example.com/sqoop\--username sqoop\--password sqoop\--table regions\ --update-key id

Sqoop export\--connect JDBC:Mysql://mysql.example.com/sqoop\--username sqoop\--password sqoop\--table regions\ --update-key id\--update-mode alloy insert
