[FLINK-6833] [task] Fail StreamTask only due to async exception if it is
running
In order to resolve a race condition between a properly terminated
StreamTask which
cleans up its resources (stopping asynchronous operations, etc.) and a
cancelled
asynchronous operation (e.g. asynchronous checkpointing operation), we
check whether
the StreamTask is still running before failing it externally.
