Gary Yao commented on FLINK-15504:
----------------------------------
Thanks for the quick reply. Considering that we have more than twice as many
release notes in 1.10 compared to 1.9, I would like not to expand the release
notes further. Moreover, we have closed hundreds of bug issues for 1.10.0 which
are not mentioned in the release notes in the user docs and some have arguably
as much impact is this issue. A list of all issues grouped by issue type [1]
will be published with the release blog post.

> Flink uses the {{OptimizerPlanEnvironment}} which replaces stdout/stderr
> during job graph creation. This was intended only for previewing the plan,
> but other parts of Flink, e.g. the Rest API have started to use this code as
> well.
> It may be acceptable to suppress output during plan preview, but we should
> not suppress the output during execution, e.g. via the REST API.
