[FLINK-3800] [jobmanager] Terminate ExecutionGraphs properly This PR terminates the ExecutionGraphs properly without restarts when the JobManager calls cancelAndClearEverything. It is achieved by allowing the method to be only called with an SuppressRestartsException. The SuppressRestartsException will disable the restart strategy of the respective ExecutionGraph. This is important because the root cause could be a different exception. In order to avoid race conditions, the restart strategy has to be checked twice whether it allows to restart the job: Once before and once after the job has transitioned to the state RESTARTING. This avoids that ExecutionGraphs can become orphans. Furthermore, this PR fixes the problem that the default restart strategy is shared by multiple jobs. The problem is solved by introducing a RestartStrategyFactory which creates for every job its own instance of a RestartStrategy. - [X] General - The pull request references the related JIRA issue - The pull request addresses only one issue - Each commit in the PR has a meaningful commit message - [X] Tests & Build - Functionality added by the pull request is covered by tests - `mvn clean verify` has been executed successfully locally or a Travis build has passed You can merge this pull request into a Git repository by running: $ git pull https://github.com/tillrohrmann/flink fixJobRestart Alternatively you can review and apply these changes as the patch at: https://github.com/apache/flink/pull/1923.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 #1923 ---- commit ea05ae102428f6be8db4091b849b680112099c36 Author: Till Rohrmann <trohrm...@apache.org> Date: 2016-04-21T15:07:51Z [FLINK-3800] [jobmanager] Terminate ExecutionGraphs properly This PR terminates the ExecutionGraphs properly without restarts when the JobManager calls cancelAndClearEverything.
