------------------------------------

             Summary: Memory leak in SavepointITCase and SavepointMigrationTestBase
                 Key: FLINK-12285
                 URL: https://issues.apache.org/jira/browse/FLINK-12285
             Project: Flink
          Issue Type: Bug
          Components: Tests
            Reporter: Xiaogang Shi
            Assignee: Biao Liu


The tests in {{SavepointITCase}} and {{SavepointMigrationTestBase}} do not cancel running jobs before exit. It will cause exceptions in {{TaskExecutor}}s and unreleased memory segments. Succeeding tests may fail due to insufficient amount of memory.

The problem is caused by cancelling {{TaskExecutor}}s with running tasks. Another issue caused by the reason can be seen in FLINK-11343. Maybe we can find a more dedicated method to cancel those {{TaskExecutor}}s still having running tasks.
