Properties have to have only different names

[Sergey Kraynev]

Currently you could define template with resources, which have same names.
However as result you will get only second definition of this resource.
I think that it's incorrect behavior and should be caught during validation.

As example try next template:

heat_template_version: 2013-05-23

resources:
  compute_instance:
    type: OS::Nova::Server
    properties:
        name: Hello1
        key_name : heat_key
        image : fedora-20.x86_64
        flavor: m1.small
  compute_instance:
    type: OS::Nova::Server
    properties:
        name: hello2
        key_name : heat_key
        image : fedora-20.x86_64
        flavor: m1.small

skr@devstack:~$ nova list
+--------------------------------------+--------+--------+------------+-------------+------------------+
| ID | Name | Status | Task State | Power State | Networks |
+--------------------------------------+--------+--------+------------+-------------+------------------+
| 58d389b0-bbe6-4be6-ae30-6e5e72bac5e8 | hello2 | ACTIVE | - | Running | private=10.0.0.5 |

Also same validation should be added for parameters (https://bugs.launchpad.net/heat/+bug/1308400) and outputs sections (https://bugs.launchpad.net/heat/+bug/1308401)

HI, jui chandwaskar. I tolerate, that somebody takes bug assigned on another person without any questions.... (but it is still roughly).

Another issues, that this can not be fixed normally without fix in pyyaml library (look bug above). So I don't see any reason, why you take it so fast.

Hi,

Thought of it from heat source.

Yes checked the above pyyaml library bug now, so will wait for the fix.
