SAMZA-1789: unify ApplicationDescriptor and ApplicationRunner for high- and low-level APIs in YARN and standalone environment This is the initial PR for SEP-13. High-lighted changes: - Define StreamApplication and TaskApplication with describe(ApplicationDescriptor) API to define processing logic of a Stream application - the objects instantiated and registered to ApplicationDescriptor in describe() method should be serializable - Define ApplicationRunner to have mandatory constructor parameter of ApplicationDescriptor - Define ProcessorLifecycleListenerFactory to allow user inject local logic and instantiate local objects in the processors in an application You can merge this pull request into a Git repository by running: $ git pull https://github.com/nickpan47/samza app-runtime-with-processor-callbacks Alternatively you can review and apply these changes as the patch at: https://github.com/apache/samza/pull/606.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #606 ---- commit 8e6fc2dac5af11f0748fdcd32175c2ae95418fc7 Author: prateekm <prateekm@...> Date: 2018-06-09T22:01:10Z Remove all usages of StreamSpec and ApplicationRunner from the operator spec and impl layers. commit 7d7aa50882d656143ea6fbc8064aca390024dd31 Author: Prateek Maheshwari <pmaheshwari@...> Date: 2018-06-13T19:56:51Z Updated with Cameron and Daniel's feedback. commit 8561930133a0da52061bceee3596d02c6c7f9370 Author: Prateek Maheshwari <prateekm@...> Date: 2018-06-15T22:25:50Z Merge branch 'master' into stream-spec-cleanup commit 7e71dc7e04c5e1a0357663a76068d3dead4ebfd8 Author: Yi Pan (Data Infrastructure) <yipan@...> Date: 2018-06-27T22:22:17Z Merge with master commit f1cb8f0eb29feefe7e01c4a159f8792b5df0ce39 Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-07-10T17:55:20Z Merge branch 'master' into single-app-api-May-21-18 commit d43e923192b8b78a9eb6ba4ba15a05151ec457f2 Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-07-11T04:30:12Z WIP: proto-type with ApplicationRunnable and no ApplicationRunner exposed to user commit 42782d815133ee75757c831f60a67f6980069e18 Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-07-17T21:54:06Z Merge branch 'prateek-remove-app-runner-stream-spec' into app-spec-with-app-runtime-Jul-16-18 commit 95577b74c7330f11ee055c363b944c745f034ee0 Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-07-18T10:09:52Z WIP: trying to figure out the two interface classes for spec: a) spec builder in init(); b) spec reader in all other lifecycle methods commit 30a4e5f0ae6ff1b99fc8a6d08e742d8bff06e0cb Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-07-23T09:02:06Z WIP: application runner refactor - proto-type for SEP-13 commit fb1bc49e04c5a420c22c3589c39eb08a2964d01d Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-07-30T20:55:59Z Merge branch 'master' into app-spec-with-app-runtime-Jul-16-18 commit 973eb5261432da50a3540c96a101136f9c854f1d Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-08-03T19:08:30Z WIP: compiles, still working on LocalContainerRunner refactor commit f20cdcda68ebf96924ece4ad16fbe25a9b370323 Author: Yi Pan (Data Infrastructure) <nickpan47@...> Date: 2018-08-06T08:32:03Z WIP: adding unit tests.
