Mysql query hangs on import
I suspect you're suffering 'out-of-the-box' syndrome. For the whole world to know... MySQL config out of the box sucks. 

Go to https://tools.percona.com/wizard and create better configuration based on the questions asked in the form. This should provide you with a better starting point. Once the output is generated, add it to your configuration file (/etc/my.cnf) and restart MySQL; review the mysql error log to ensure that your mysql instance started cleanly (beware of paths, permissions and the innodb_log_file_size size differences since that will require disposal of the old ib_log* files before new ones can be created). Once done, try your import again.
