Hi, We have deployed a Mesos cluster with Marathon, we deploy flink sessions through marathon with multiple taskmanagers configured. Some times in previous stages usually change configuration on marathon json about memory and other stuff, but when redeploy the flink session the jobmanagers stop and start with new configuration, but the taskmanagers not reuse the same was configured. So we have to kill/stop the dockers of each taskmanager task.
There is a way that kill or stop the taskmanagers when the session is redeployed? Some environment configuration from marathon json file related to taskmanagers: ``` "flink_akka.ask.timeout": "1min", "flink_akka.framesize": "102400k", "flink_high-availability": "zookeeper", "flink_high-availability.zookeeper.path.root": "/flink", "flink_jobmanager.web.history": "200", "flink_mesos.failover-timeout": "86400", "flink_mesos.initial-tasks": "16", "flink_mesos.maximum-failed-tasks": "-1", "flink_mesos.resourcemanager.tasks.container.type": "docker", "flink_mesos.resourcemanager.tasks.mem": "6144", "flink_metrics.reporters": "jmx", "flink_metrics.reporter.jmx.class": "org.apache.flink.metrics.jmx.JMXReporter", "flink_state.backend": "org.apache.flink.contrib.streaming.state.RocksDBStateBackendFactory", "flink_taskmanager.maxRegistrationDuration": "10 min", "flink_taskmanager.network.numberOfBuffers": "8192", "flink_jobmanager.heap.mb": "768", "flink_taskmanager.debug.memory.startLogThread": "true", "flink_mesos.resourcemanager.tasks.cpus": "1.3", "flink_env.java.opts.taskmanager": "-XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:ConcGCThreads=1 -XX:InitiatingHeapOccupancyPercent=35 -XX:G1HeapRegionSize=16M -XX:MinMetaspaceFreeRatio=50 -XX:MaxMetaspaceFreeRatio=80 -XX:+DisableExplicitGC -Djava.awt.headless=true -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=10M", "flink_containerized.heap-cutoff-ratio": "0.67" ``` Thanks in advance and kind regards, Manuel Montesino Devops Engineer E manuel.montesino@piksel(dot)com Marie Curie,1.
