Re: [ANNOUNCE] Apache Flink 1.9.1 released

Hi Thomas Weise

We have an issue related to this problem
https://issues.apache.org/jira/browse/FLINK-14147, but I think you could
open another JIRA
The watermark data comes from metric REST API, which is too heavy for high
parallelism jobs, the API almost sure will break when the parallelism is
too high
We could hide the error message as a temp solution and refactor the API to
solve this issue completely later.
