------------------------------------
Summary: Let Task release reference to Invokable on shutdown
Key: FLINK-10033
URL: https://issues.apache.org/jira/browse/FLINK-10033
Project: Flink
Issue Type: Bug
Components: TaskManager
Affects Versions: 1.5.2
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.5.3, 1.6.0
References to Task objects may under some conditions linger longer than for the
lifetime of the task. For example, in case of local network channels, the
receiving task may have a reference to the object of the task that produced the
data.
To prevent against memory leaks, the Task needs to release all references to
its AbstractInvokable when it shuts down or cancels.
