I have Flink Kafka Consumer in place which works fine until I add the below lines:
env.setRestartStrategy(RestartStrategies.failureRateRestart( 3, *// max failures per unit* Time.of(5, TimeUnit.MINUTES), *//time interval for measuring failure rate* Time.of(10, TimeUnit.SECONDS) *// delay*)) It gives me the below error stack trace: DEBUG [flink-akka.actor.default-dispatcher-14] (JobMaster.java:1119) - Close ResourceManager connection 05d80aa9f3aca06faf7be80bbc8a0642. org.apache.flink.util.FlinkException: Stopping JobMaster for job Flink Kafka Example(b425ae91bfb0e81980b878b3e4392137). at org.apache.flink.runtime.jobmaster.JobMaster.onStop(JobMaster.java:400) at org.apache.flink.runtime.rpc.RpcEndpoint.internalCallOnStop(RpcEndpoint.java:214) at org.apache.flink.runtime.rpc.akka.AkkaRpcActor$StartedState.terminate(AkkaRpcActor.java:563) at org.apache.flink.runtime.rpc.akka.AkkaRpcActor.handleControlMessage(AkkaRpcActor.java:186) at akka.japi.pf.UnitCaseStatement.apply(CaseStatements.scala:26) at akka.japi.pf.UnitCaseStatement.apply(CaseStatements.scala:21) at scala.PartialFunction$class.applyOrElse(PartialFunction.scala:123) at akka.japi.pf.UnitCaseStatement.applyOrElse(CaseStatements.scala:21) at scala.PartialFunction$OrElse.applyOrElse(PartialFunction.scala:170) at scala.PartialFunction$OrElse.applyOrElse(PartialFunction.scala:171) at akka.actor.Actor$class.aroundReceive(Actor.scala:517) at akka.actor.AbstractActor.aroundReceive(AbstractActor.scala:225) at akka.actor.ActorCell.receiveMessage(ActorCell.scala:592) at akka.actor.ActorCell.invoke(ActorCell.scala:561) at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:258) at akka.dispatch.Mailbox.run(Mailbox.scala:225) at akka.dispatch.Mailbox.exec(Mailbox.scala:235) at akka.dispatch.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) at akka.dispatch.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) at akka.dispatch.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) at akka.dispatch.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) DEBUG [flink-akka.actor.default-dispatcher-12] (DefaultJobLeaderIdService.java:148) - Remove job b425ae91bfb0e81980b878b3e4392137 from job leader id monitoring.

This property is set at the last while setting the configuration. Does the ordering matter? or what else am I missing? I am using Flink 1.13.5 Thanks, Sid
