	Middle	The books says about "lastmodified" mode the following: Internally, the lastmodified incremental import consists of two standalone MapReduce jobs. The first job will import the delta of changed data similarly to normal import. This import job will save data in a temporary directory on HDFS. The second job will take both the old and new data and will merge them together into the final output, preserving only the last updated value for each row. I think Sqoop does not merge anything without explicitily specifying the operation sqoop merge.	Anonymous	Mar 14, 2018

Printed	Page 14 Last source code block	In the book, the first command to create a password file is echo "my-secret-password" > sqoop.password. This command adds at the end of the password an end-of-line, which will be part of the password. To avoid that, the command has to be changed to echo -n "my-secret-password" > sqoop.password	Vincenzo Manzoni	Jun 23, 2016
