Hi All, In 1 of our cluster , we enabled Istio where spark is running in distributed mode. Spark works fine when we run it with Istio in standalone mode. In spark distributed mode , we are seeing that every 1 hour or so the workers are getting disassociated from master and then master is not able to spawn any jobs on these workers , until we restart spark rest server.
Here is the error we see in the worker logs: *ERROR CoarseGrainedExecutorBackend: Executor self-exiting due to : Driver spark-rest-service:44463 disassociated! Shutting down.* For 1 hour or so (until this issue happens) , spark distributed mode works just fine. Thanks Deepak
