Subject Flink -mesos-app master hang
Date Sun, 30 Jul 2017 19:42:43 GMT
Hi All,
I'm trying to run a flink docker from the marathon with mesos app master; I
could see it goes on a continuous loop and failed to launch the task
manger. If I go to mesos master UI I could see job manager web UI with task
manager zero .

I have pretty much checked every possible log starting from Ubuntu machine
docker.log /mesos master/slave  pretty much no information other than just
failed task , I could see below log @ flink . However, I'm able to run same
docker image if I run jobamanger and taskmanager by itself in marathon and
let it connect via jobmanager RPC port .

for mesos config , I'm using below details from yml
mesos.master: ${MESOS_MASTER}
mesos.failover-timeout: 60
mesos.initial-tasks: ${INITIAL_TASK_MANAGERS}
mesos.resourcemanager.tasks.mem: ${RESOURCEMANAGER_TASKS_MEM:-4096}
mesos.resourcemanager.tasks.cpus:${RESOURCEMANAGER_TASKS_CPU:-1}
mesos.resourcemanager.tasks.container.type: docker
mesos.resourcemanager.tasks.container.image.name: ${IMAGE_NAME}

---------------------------
07-30 02:05:48,351 WARN
org.apache.flink.mesos.scheduler.TaskMonitor                  - Mesos task
taskmanager-00002 failed unexpectedly.

- Mesos task taskmanager-00002 failed, with a TaskManager in launch or
registration. State: TASK_FAILED Reason: REASON_COMMAND_EXECUTOR_FAILED
(Container exited with status 127)
-----------------------------------------------------

Please let me know if any one has any pointer to debug further ..
