Failure Callback

[kapil-malik]

We have a requirement that whenever a submitted job is over, our REST endpoint should get a callback for the same.
For jobs which are successfully completed, a small dependent job is good to make this work.
However, for failed jobs, the dependent job is not triggered. Is there any way / any plans to support a failure callback endpoint in Chronos?

Hi,
Is there any update on this?

@kapil-malik So are you suggesting another chronos job that runs when one of your steps failed?
I think this is going to be very basic functionality that most people will need, let me see if the Chronos team has planned this or perhaps it's already in Chronos.

Also can you perhaps elaborate more at what stage you like a failure job to happen? And what does that failure job features requirements will look like (Another depednency job chain in chronos, with/without schedule, etc) for you?

Hi @tnachen
While I am using a dependent job for success callback, ideally I would want to schedule 'Chronos job' only for the application logic. For my usecase, a success / failure callback can be simply a REST callback, something like marathon.
On the other hand, what you mention is also interesting, a way of conditional execution. Job A -> success = Job B, failure = Job C etc. But I believe this will require more work in Chronos (to design and implement all possible ways of conditional execution).

Hi @tnachen
I submitted a pull request for this issue. #518
Can you kindly have a look and provide comments / accept it?

Thanks,
