    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost/metastore?createDatabaseIfNotExist=true</value>

When I executed schematool -initSchema -dbType mysql everything is fine. It initialize the 2.3.0 schema of hive. when I started hive and execute the command show databases; or any other, I got this errors

hive> show databases;
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is
generally unnecessary.

What version of Hadoop are you using? Might have to do with incompatible version of hadoop
