------------------------------------
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.
