Review comment:
Can you explain the reasoning behind removing this branch?
I think we still need it, because if the user doesn't set a timeout for
transformation then default job timeout should be used.

Review comment:
I think adding the timeout value and `edge.toString` could help to find
out misconfguration to the user.

Review comment:
If we keep using the default timeout (discussion above),
then the issue also happens with
`StreamExecutionEnvironment.setBufferTimeout(100)` or even default, right?
