Hi, @zentol, I think just lazy init streamRecordWriters will solve the bug before, but the `StreamTaskCancellationBarrierTest#testEmitCancellationBarrierWhenNotReady` test failed caused the travis failure.
So I checked what wrong. I find that because of the rework of Flinkās Network Stack from flink-1.5.0 version.
before flink-1.5.0 version, the `CancelCheckpointMarker message` was send by `ResultPartitionWriter`
after flink-1.5.0 version, the `CancelCheckpointMarker message` was uniformly broadcasted by `StreamRecordWriter` which inited in StreamTask's constructor.
So, I need to rethink how to solve this problem, It would be nice if I could give me some advice.
Best, lamber-ken
