Usually this is caused by not having the mysql jdbc driver on the
classpath (it's not default included in hive).
Just put the mysql jdbc driver in the hive folder under "lib/"

I've checked the mysql connection with a separate java file with the

Also, I've checked the code works by running it against the original

Thanks,

Some of the variables set:
javax.jdo.option.ConnectionURL =
jdbc:mysql://192.168.1.5/metastore?createDatabaseIfNotExist=true
<http://192.168.1.5/metastore?createDatabaseIfNotExist=true>
javax.jdo.option.ConnectionDriverName=com.mysql.jdbc.Driver
javax.jdo.option.ConnectionUserName=username
javax.jdo.option.ConnectionPassword=password
