hiliuxg commented on FLINK-15388:
---------------------------------
That error log was a colleague who asked for the job status every 10 seconds
and showed it on his webui. I've asked him to cancel it, and then watch it
again.
In addition, I found that the jobmanager will flash a warn log every 10
seconds. Is this TM's heartbeat log? Why does the link fail with only a few
machines?
