I’ve written a book “Instant Apache Sqoop”

I recently finished writing a book Instant Apache SqoopApache Sqoop is a tool which is designed for moving data between Hadoop Ecosystem and structured data stores such as relational databases.
Instant Apache Sqoop covers following topics:
  • Working with the import process
  • Incremental import
  • Populating the HBase table
  • Importing data into HBase
  • Populating the Hive table
  • Importing data into Hive
  • Working with the export process
  • Exporting data from Hive
  • Using Sqoop connectors
Instant Apache Sqoop is a practical, hands-on guide that provides you with a number of clear, step-by-step exercises that will help you to take advantage of the real power of Apache Sqoop and give you a good grounding in the knowledge required to transfer data between RDBMS and the Hadoop ecosystem.

Hi Ankit,
I have ready your book on safari today. Its really nice. I am currently working on incremental process using sqoop. Its working fine when i dont have any NULL in any of my fields but it fails to identify the updates if i update any of the columns to NULL.
After the incremental process i wcould see tow records for same ID.
ID EMP_NM Designation dates
6 emp1 NULL 2013-12-25 12:52:35.0 ---------recent update
6 emp1 ARCH 2013-12-20 03:08:04.0------------old data
Why sqoop is not able to identify that its a update for a record?
