--------------------------------------
Summary: Source thread should be interrupted during the Task
cancellation
Key: FLINK-15076
URL: https://issues.apache.org/jira/browse/FLINK-15076
Project: Flink
Issue Type: Bug
Reporter: Piotr Nowojski
Assignee: Piotr Nowojski
Fix For: 1.10.0
Source thread should be interrupted more or less the same way how task thread
is being interrupted.
+/- The `StreamTaskTest#testCancellationNotBlockedOnLock` should also work in
case if the mailbox (task) thread is blocked on trying to acquire a
`checkpointLock` by some other currently being executed mail (processing time
timer/perform checkpoint).
