Tenta trocar ( que também está escrito errado)

<property name="hibernate.hbm2ddl.auto" value="upadate"/>

para

<property name="hibernate.hbm2ddl.auto" value="create"/>

no Stacktrace ele ta avisando:

WARN: Unrecognized hbm2ddl_auto value : upadate. Supported values include create, create-drop, update, and validate. Ignoring
