Stephan Ewen commented on FLINK-22069:
--------------------------------------
There is one that doesn't yet seem to be fixed that I found really bad during
debugging: logging the full exception stack trace when a checkpoint cannot be
triggered due to the fact that some tasks are still starting up. It happens
during almost every startup, is often unavoidable, and is a completely fine and
expected situation. The stack trace makes it look scary.
