In case of a problem with the Cassandra DB connection, the job does not restart, but runs forever.
I detected this issue multiple times using a new cassandra version.
In the logs you might se an error like:
{"timestamp":"2023-11-05T23:47:55.958Z","message":"No schema agreement from live replicas after 10 s. The schema may not be up to date on some nodes.","thread":"JanusGraph Cluster-worker-0","logger":"com.datastax.driver.core.Cluster","level":"WARN","logType":"app"}
{"timestamp":"2023-11-05T23:47:55.959Z","message":"[Control connection] Refreshing schema for aaigraph.systemlog (TABLE)","thread":"JanusGraph Cluster-worker-0","logger":"c.d.driver.core.ControlConnection","level":"DEBUG","logType":"app"}
Exception in thread "main" java.lang.reflect.InvocationTargetException

but the job continues to run forever and waits for schema completion.
This will prevent the AAI components to start...
If the job would detect the problem and stops with a failure, it would be started and in many cases successfully finish.
