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

             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).
