Do you get the same response from e.g. starting a mysqld server? It's
basically the same code.
There's nothing special about the way clusterj gets a session factory
(ndb_cluster_connection) but it does require contacting the management
node and setting up tcp connections from the client node to all data
nodes. If the management node is slow, overloaded, on a slow network,
etc. I might expect the initial connection to be slow.
