Description:
When using a hostname as connect string i get the following assertion on starting 
the debug version of ndb_mgmd:

  ndb_mgmd: MgmtSrvr.cpp:2243: bool MgmtSrvr::alloc_node_id(NodeId*, ndb_mgm_node_type, sockaddr*, socklen_t*, BaseString&): Assertion `*nodeId != 0' failed.

When giving a node ID as connect string instead all seems to be fine.

How to repeat:

Cluster configuration file with 2 management server nodes

This connect string configuration leads to the assertion failure

just the nodeid alone doesn't work, too

Attachment: my.cnf (application/octet-stream, text), 280 bytes.

with both node id and server name it works

Attachment: my.cnf (application/octet-stream, text), 304 bytes.

Correction: assertion failure will only go away when specifying both node ID and host name
