From the forum:

Warning comes right after reading the persistence.xml:

WARN [org.hibernate.ogm.datastore.impl.DatastoreProviderInitiator] (ServerService Thread Pool – 72) OGM000070: 'com.example.MyDatastoreProvider' is no valid datastore provider short name. Valid values are: MAP, INFINISPAN, EHCACHE, MONGODB, NEO4J_EMBEDDED, COUCHDB_EXPERIMENTAL

This should be logged on INFO only.
