Public bug reported:

Trying to instantiate a Spark 1.0.0 cluster, using “Data Processing”
element under Horizon, and am having the following problems:

1-      Security Group: Having problem with security groups, when either
defining "Node Group Templates" or instantiating a cluster. In the first
case, if I use an existing group, say "default", gui shows an error
stating "Error Security group '2' not found". Sahara log file indicates
the same thing:

I can, temporarily, avoid the problem by selecting "Auto Security Group"
option. This would allow for a node group to be created; however, I do
not see any new security group, under Compute -> Access & Security. At
any rate, this also fails during cluster instantiation:
