I do not think we have such a function in the resource_management library.


But you can call any shell command using the Execute() function.

Hi Sumit,
Thanks for your valuable answer,
I was having one more query,
Can I use this static function or block to append some string lines from one file to another
file,
Like this File() function is used here for copying,
Is there anything we can use for appending from one file to another file.

Regards,
Rohit Kale

The files in folder package/files folders are example of static files that are available to
the service scripts to use.



This is one example of such pattern:



File(format("{dest_conf_dir}/{name}"),
  mode=0644,
  group=params.user_group,
  owner=params.accumulo_user,
  content=StaticFile(name)
)

I have just used a sample path here,
I just want to get some variable through which I can get the location or path where we install
services e.g.
“/var/lib/ambari-server/resources/stacks/HDP/2.2/services/<MY SERVICE NAME>”

  I can't catch your meaning. Where does the source file path come from?

Hi
I need a help regarding ambari custom service,
I want to add a custom service in ambari which copies a file to multiple ambari agents,
For this I want to provide variables for file path in python scripts, these python scripts
get called by the service.
I want to get some variable or a way by which I can use the relative path for copying my file
For e.g. I want to copy a file from location X to Y in python script
X location in contained in some ambari folder let’s say “/var/lib/ambari-server/resources/stacks/HDP/2.2/services/<MY
SERVICE NAME>/my_sample_file.txt”
Y location some location in same node say “/tmp/”

I want that I can fetch X location by some variable so that I can use to copy like:
Copy  some_variable_name/my_sample_file.txt   /tmp/

Can someone help me in this, I tried using “../../” relative path but it doesn’t work.

Regards,
Rohit Kale
