[hibernate-dev] [OGM-122] Cassandra integration and hibernate-core version

[kmx.petals at gmail.com]

Hi,

I am trying to integrate Cassandra into Hibernate OGM (cf. issue 
OGM-122) and as I am a noob, I have some noob questions...

Presently, the current version of Hibernate OGM is using the version 
4.0.1-Final of Hibernate core but this version seems to call twice the 
start method from CassandraDatastoreProvider.

Indeed, in the method initializeService() from the class 
AbstractServiceRegistryImpl, the phase 4 which is starting the service 
(and so the CassandraDatastoreProvider) is calling twice startService :

// PHASE 4 : Start service
serviceBinding.getLifecycleOwner().startService( serviceBinding );
startService( serviceBinding );

As the start method of CassandraDatastoreProvider is optionaly creating 
the keyspace and initializing the columnFamily, this is done twice and 
is not what is expected.

However, in the version 4.1.1-Final of Hibernate-core, the second call 
is not done.

Is it a real issue and what are the consequences in the ingration of 
other NoSQL products?

Should Hibernate OGM move to Hibernate-core 4.1.1+?
(I already made the work to test but I am not sure of consequence since 
interfaces changed -ex: SessionFactoryImplementor or EntityPersister) 
but it seems to work ;-)
