Thanks for your explanation.
Sure, I will create an issue on JIRA.

Slider can allocate unique port for each component instance. There is a
mechanism for an app instance to publish configuration through a registry.
If I am guessing correctly, each Vertica node is of the same component type
and currently Slider does not have the ability to advertise different info
for each instance of the component.
Incidentally, we identified it as a requirement as any application that is
essentially a set of peers you will need to know the listen port for all
instances. This is typically mitigated by assigning the same port but to
take full advantage of YARN hosting its best to allow dynamic port
allocation. So we will add the capability soon. Can you open a JIRA and
describe the scenario from your perspective?
thanks

My command should set the port number for my application. So if Slider
allocates the port number for it, I don't need to set it in the python
script any more, right?
Vertica nodes are peers and can all be connected by clients. The dba needs
to know the port number of every Vertica node.
Thanks.

If there is a need for advertising the port numbers on a per role instance
basis then that is not supported - we would like to understand if there is
a need such a capability.

Hi,
If Slider give me containers on the same machine for the same role of my
application. Is it possible for the python agents in Slider to know there
are the same roles that are going to be started in the same machine and
avoid the port conflicts?
If there are already the same roles running, I can check by catching the
exception easily. What if multiple same roles are starting
simultaneously?
Thanks,
