Hi, I have come across an issue related to GET /job/:jobId endpoint from monitoring REST API in Flink 1.9.0. A few seconds after successfully starting a job and confirming its status as RUNNING, that endpoint would return 404 (Not Found). Interestingly, querying immediately again (literally a millisecond later) would return a valid result. I later noticed a similar behaviour in regard to a finished job as well. At certain points in time that endpoint would arbitrarily return 404, but similarly querying again would succeed. I saw this strange behaviour only recently and it used to work fine before.
Do you know what could be the root cause of this? At the moment, as a workaround I just query a job a couple of times in a row to ensure whether it definitely does not exist or it is just being misreported as non-existent, but this feels a bit like cottage industry...
