What does "owner of this database" mean? There's no such concept
in the MySQL permission system. And how did you figure out that
user1 owned a particular database? Do you mean that the export
file created was owned by the OS user 'user1'?

>But I would like to import this same database with user2.

If this is an issue of OS file ownership, run the export as user2.

Note: OS users and MySQL users are not necessarily related to each
other and there need not be any overlap between the names. A given
OS user can run as any MySQL user (assuming he knows the password)
using the -u and -p options to the MySQL command-line utility or
mysqldump.
