Hello, I noticed my Flink Cluster (version 1.16) is uploading a jar called “check-execute.jar” itself regularly. Apparently it also tries to run it, at least that’s what I take from this log of my jobmanager that appears numerous times:
2023-01-16 07:09:00,719 WARN
org.apache.flink.runtime.webmonitor.handlers.JarRunHandler [] - Configuring
the job submission via query parameters is deprecated. Please migrate to
submitting a JSON request instead.
2023-01-16 07:09:00,733 INFO org.apache.flink.client.ClientUtils
[] - Starting program (detached: true)
2023-01-16 07:09:01,362 ERROR
org.apache.flink.runtime.webmonitor.handlers.JarRunHandler [] - Exception
occurred in REST handler: No jobs included in application.
I wonder if this is expected behavior, maybe for the system to assert its
functionality. It would be very kind if someone could enlighten me here, I
tried to find what this is about in the source code of Flink, but was not able
to find anything.
Kind regards
