@doriordan This PR is ready for you to review. I've used it at JPL quite effectively! |

Thanks for the PR Nicolas, I will look to review it in the next day or two. |

I haven't had a chance to finish reviewing the changes as I am travelling, but have made some comments on the overall direction of the PR.
As per one of my comments, I am currently working on a list/watch specific API and we coud consider whether your changes could be somehow brought into that, although it is not ready for review/release itself yet.

Would it be possible to submit the various build updates as a separate PR, unless those updates are required by the other changes?
(I find small, cohesive PRs generally are best)

The .travis.yml file is currently broken; see: https://travis-ci.community/t/install-of-oracle-jdk-8-failing/3038
Do you want to fix the .travis.yml file as part of a separate issue? If so, this PR will fail until the travis ci issue is resolved.

I'm reluctant to modify the existing watch methods API signatures here, it affects all clients. In fact, because there are other watch related enhancements that I am working on, I plan to add a single new method to the existing API which will return a separate API object for some new/enhanced watch/list related functionality. That new API might be the right place to consider this new pool parameter.

The current API completely hides the fact that there's a pool involved and therefore prevents doing anything with it:
- reuse the same across multiple calls (see the PiJobsSequential example)
- create an independent pool for each call (see the PiJobsParallel example)
- shutting down a pool when it is no longer needed
If you're thinking of refactoring this API, it would be good to keep the above use cases in mind; the distinction between sequential & parallel invocations of long-duration operations is very important for us.
I don't know how to support these use cases without changing the API in some incompatible way. Please advise how you want to proceed. I'm OK in deferring action until you refactor the API as you mentioned.

In general I try to keep the API generic in regards to resource types, which reflects the actual Kubernetes REST API design largely (exception of some specific methods on pods such as exec). This is specific to Job resources, so again my thoughts are that it could be implemented in the examples sub-project.

why not use watch here instead of polling?

This repo seems to have been abandoned. Thanks, |
This PR addresses the intent of #280 with two API-breaking changes:
The long-duration
watch...operations have a different signature to allow passing an optional pool and for returning a skuber pool that can be used for long-duration calls to the same server and the underlying akka connection pool that can be shutdown when no more calls to the same server are needed.New API operations to facilitate the following:
Note that due to licensing changes in Oracle JDK8, the Travis CI config had to be updated.
Also, updated to Scala 2.12.8 and Akka 2.5.23
