How to import a fixed number of rows in incremental import in sqoop?
I am learning sqoop on my own and tried to locally test the incremental import functionality by using the below mentioned code
sqoop import
--connect jdbc:mysql://localhost/employees
--username root
-P
--query 'select * from employees WHERE $CONDITIONS ORDER BY emp_no LIMIT 1000'
-m 1
--incremental append
--check-column emp_no
--target-dir sqoop/import_data/employee_db_import_incremental
The above piece of script imported the first 1000 records and now I want to append the next 1000 records to the existing data. How to do it ?
mysql hadoop mapreduce sqoop

You must specify the last value, from which record you need to append, suppose your last record is 1000
then your command must be like following:
sqoop import
--connect jdbc:mysql://localhost/employees
--username root
-P
--query 'select * from employees WHERE $CONDITIONS ORDER BY emp_no LIMIT 2000'
-m 1
--incremental append
--check-column emp_no
--last-value 1000
--target-dir sqoop/import_data/employee_db_import_incremental
