Description

The behavior of --fetch-size has been changed in SQOOP-1400 and reverted in SQOOP-1617 as follows:

• Prior to SQOOP-1400: row-by-row is the default
• With SQOOP-1400: load everything is the default
• SQOOP-1617 and higher: row-by-row becomes the default again

The behavior of the option with MySQL is a bit different from the other drivers because MySQL JDBC driver can only handle row-by-row or load-everything. So that it should be documented in the area of the limitation.
