[StarCluster] Starcluster stuck during setup

[Cory Dolphin]

Whenever I try and add a node to a spot instance cluster, starcluster does
not properly wait for the spot request to be fulfilled, and instead errors
out:

starcluster addnode mycluster
StarCluster - (http://star.mit.edu/cluster) (v. 0.95.3)
Software Tools for Academics and Researchers (STAR)
Please submit bug reports to starcluster at mit.edu

>>> Launching node(s): node030
SpotInstanceRequest:sir-85f44249
>>> Waiting for spot requests to propagate...
>>> Waiting for node(s) to come up... (updating every 30s)
>>> Waiting for all nodes to be in a 'running' state...
30/30 ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
100%
>>> Waiting for SSH to come up on all nodes...
30/30 ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
100%
>>> Waiting for cluster to come up took 1.179 mins
!!! ERROR - node 'node030' does not exist


Once the spot instance request is fulfilled, the instance does not have a
name. Looks like someone else had this problem quite
recently<http://star.mit.edu/cluster/mlarchives/2058.html>.
I wonder what the difference between our setup and yours is?
