Seems social-core is unable to read the datasource in-order to return the connection. Not sure weather this occurred due to the exact reason you mentioned above. You can debug the social-core and see what is going wrong here. You need to get source related to this component from a old commit since we don't maintain this Cassandra based implementation now.
As I can remember we had this component during 1.0.0, es-1.0.2 releases[1].
