Jiangjie Qin updated FLINK-20492:
---------------------------------
Description:
The {{SourceOperatorStreamTask}} does not implement {{cancelTask}} and
{{finishTask}} at this point. This causes resource leak on job cancellation of
finish.
Currently there are three cases that a Job may exit.
# Canceled - {{cancelTask()}} method will be called to close the
SourceOperator.
# Stopped with a savepoint - {{finishTask()}} method will be called to close
the SourceOperator.
# Runs to the EndOfInput - the SourceOperator is closed in
{{StreamTask.afterInvoke()}}.
was:The {{SourceOperatorStreamTask}} does not implement {{cancelTask}} and
{{finishTask}} at this point. This causes resource leak on job cancellation of
finish.
> The SourceOperatorStreamTask should implement cancelTask() and finishTask()
