How reproducible is this problem / how often does it occur?
How is the cluster deployed?
Is anything else happening to the cluster around that that time (like a
JobMaster failure)?

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…
Kind regards,
Tomasz
