Better to check explicitly with if callback_url is not None:
| raise ApiException(ex.status, ex.reason) | ||
| is_all_pods_running = False | ||
| status, is_all_pods_running = self.get_status(is_all_pods_running) | ||
| # notify the callback receiver that the job is running |

I think the code is obvious enough that it doesn't need a comment. I think the same goes for all other places where you call callback.send(), perhaps with the exception of this comment in the taskmaster module:
# send "SYSTEM_ERROR" to callback receiver if taskmaster completes
# but the output filer fails
| self.body['metadata']['name'] = self.name | ||
| self.callback = None | ||
| if callback_url: | ||
| task_name = '-'.join(name.split('-')[:2]) |

Not quite sure why you process the task name. Is the processed version the one that the user knows (i.e., the one that is returned when POSTing a new task)?

Again, better to compare explicity against None, i.e., if self.callback is not None [...]. Same below.

I don't quite understand this code. At this stage, CallbackSender misses required information, the URL and the task name. Now, it appears that this is filled in when newParser() is called. But when does that happen? And who/what sets the environment variable CALLBACK_URL and when? And can you be sure that data['executors'][0]['metadata']['labels']['taskmaster-name'] is always set and correct when newParser() is called? And can you be sure that callback.url and callback.task_id are always set (and correctly) whenever callback.send is called?

Also, setting callback as a global and changing it in newParser() is quite a side effect. Wouldn't it be better to add a setter method to CallbackSender and call that somewhere (ideally not in newParser() itself, but in the context where newParser() is called?

I guess instead of a while loop you could use a for loop with range(number_of_retries). That way you could get rid of retries and manual incrementing. You could also use break instead of sent = True and get rid of sent.

Might be good to log something here.

What is the task ID is not set?

At this point you already have a callback instance. Why not use that?

Thanks @sgalpha01. Added some comments. Most are minor style/best practice things, in others I'm just asking for clarification because I don't know the TESK codebase well |

Updated taskmaster to take
callback_urland send notifications to the callback receiver on status change.
