save points through REST API not supported ?

Vishal Santoshi
One can submit jobs, upload jars, kill jobs etc very strange that you can’t do a save point ?

Or am I missing something obvious ?

I was more interested in savepoints WITHOUT cancellation...

Hi. 

It is not possible through REST in Flink 1.3.2 I’m looking for the feature. The only option is to use ./Flink savepoint for now

Is that something 1.4 has?

Re: save points through REST API not supported ?

No, this is also not possible in 1.4.

This will be available in 1.5 where we rework the client-cluster communication to go entirely through the REST API.
This will mean that everything you can do with the command-line client can also be achieved directly through the REST API.

However, from what i can tell this should be straight-forward to implement in a custom build. I can take a deeper look if this would be an acceptable workaround for you.

Re: save points through REST API not supported ?

Chesnay Schepler
I've finished the implementation. I created 2 new branches in my repository, for 1.3.2 and 1.4.

1.3.2: https://github.com/zentol/flink/tree/release-1.3.2-custom
1.4: https://github.com/zentol/flink/tree/release-1.4-custom

Triggering savepoints works exactly like cancel-with-savepoint, just replace "cancel-with-savepoint" with "trigger-savepoint" in the URL.
  • "/jobs/:jobid/trigger-savepoint"
  • "/jobs/:jobid/trigger-savepoint/target-directory/:targetDirectory"
  • "/jobs/:jobid/trigger-savepoint/in-progress/:requestId"

Re: save points through REST API not supported ?

Chesnay Schepler
In retrospect I'm quite frustrated we didn't get around to implementing this for 1.4.
The least-effort implementation would have required copying one class, and modifying ~10 lines.

Doesn't get any more low-hanging than that.

Re: save points through REST API not supported ?

Lasse Nedergaard
I hope it can be put in 1.4.1. 

I have one concern about the rest api. We running 1.3.1 on dc/os and if we apply parameters as arguments and in our code validate these parameters and throw an exception during startup if something is wrong we see that all uploaded jar disappear all running jobs are gone and sometimes we loss all the task managers. I don’t think it is the attended behaviour.

Could that be put into 1.4 release ? This significantly eases tooling  around savepoints and though a minor change it is not intrusive or should cause regression.. thank you though...

Re: save points through REST API not supported ?

Fabian Hueske-2
We are currently voting on the third release candidate for 1.4.0.

Feel free to propose this feature on the dev mailing list [1], but I don't think this will result in cancelling the vote.
If we identify a blocking issue for 1.4.0, it could be included as well. But we're already a few weeks behind schedule and 1.5.0 is supposed to be released in February 2018.
1.4.1 might be also debatable.

Best, Fabian
