Re: hostname param for slave

[Alejandro Fernandez]

Typically, a template file will reference a python variable, e.g., 
{{slave_hosts}}
In params.py or params_linux.py, you can define slave_hosts = 
default("/clusterHostInfo/my_component_hosts", [])

Thanks,
Alejandro

Subject: Re: hostname param for slave

I would also like to know the answer to this.

I would like to add on to this a bit... is there a way to know at install time 
for the service to know all the nodes it is being installed on?

Thanks!

How can I get the HOSTNAME of the specific hosts on which the slave 
component is being installed in to the template file.

hostname param for slave

[Satyanarayana Jampa]

Hi,
I have written a Ambari service which is a slave component.
In this service, I have a template which is my configuration file. This 
file needs the "hostname" as one of its field.
   Example template below:
host = ''
  accesslog = '/opt/purple/accesslog.out'
   errorlog = '/opt/purple/gunicorn.out'

How can I get the HOSTNAME of the specific hosts on which the slave 
component is being installed in to the template file.

Thanks,
Satya.
