Till Rohrmann updated FLINK-12285:
----------------------------------
Component/s: Runtime / Coordination
> Memory leak in SavepointITCase and SavepointMigrationTestBase
> -------------------------------------------------------------
>
> Key: FLINK-12285
> URL: https://issues.apache.org/jira/browse/FLINK-12285
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination, Tests
> Reporter: Xiaogang Shi
> Assignee: Biao Liu
> Priority: Critical
> Labels: pull-request-available, test-stability
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
