-----------------------------------
Description:
Hi team. We have just upgraded flink-k8s-operator to 1.12.1 and discovered that
for flink jobs running v.1_17 or earlier, there are such error logs in operator:

for jobs running on flink v1.18 and above, I don't see such errors.
To reproduce: apply FlinkDeployment to k8s, wait for job to run, then kill task
manager manually. In UI you can see job exception in exception history.
Operator will start to produce errors in a loop.
I'm not sure what are negative consequences of these errors.
The same issue was raised in mailing list:
