Nicholas Chammas updated SPARK-1805:
------------------------------------
         Description: In the current EC2 script, the AMI image object is loaded 
only once. This is OK when the master and slave machines are of the same 
virtualization type (pv or hvm). But this won't work if, say, the master is pv 
and the slaves are hvm since the AMI is not compatible across these two kinds 
of virtualization.  (was: In current EC2 script, the AMI image object is loaded 
only once. This is ok when master and slave machines are of the same 
visualization type (pvm or hvm). But this won't work if, say, master is pvm and 
slaves are hvm since the AMI is not compatible between these two kinds of 
visualization. )
    Target Version/s: 1.3.0
             Summary: Error launching cluster when master and slave machines 
are of different virtualization types  (was: Error launching cluster when 
master and slaves machines are of different visualization types)
