Subject Running Flink on Marathon
Date Sun, 28 Apr 2019 07:56:39 GMT
I have three physical nodes with docker installed on them. I have one docker
container with Mesos, Marathon, Hadoop and Flink. I configured Master node
and Slave nodes for Mesos,Zookeeper and Marathon. I do these works step by
step. First, In Master node, I enter to docker container with this command:

docker run -v /home/user/.ssh:/root/.ssh --privileged -p 5050:5050 -p
5051:5051 -p 5052:5052 -p 2181:2181 -p 8082:8081 -p 6123:6123 -p 8080:8080
-p 50090:50090 -p 50070:50070 -p 9000:9000 -p 2888:2888 -p 3888:3888 -p
4041:4040 -p 7077:7077 -p 52222:22 -e WEAVE_CIDR=10.32.0.2/12 -e
MESOS_EXECUTOR_REGISTRATION_TIMEOUT=5mins -e LIBPROCESS_IP=10.32.0.2 -e
MESOS_RESOURCES=ports*:[11000-11999] -ti hadoop_marathon_mesos_flink_2
/bin/bash

Then run Mesos and Zookeeper :

/home/zookeeper-3.4.14/bin/zkServer.sh restart
/home/mesos-1.7.2/build/bin/mesos-master.sh --ip=10.32.0.1
--hostname=10.32.0.1 --roles=marathon,flink --quorum=1
--work_dir=/var/run/mesos --log_dir=/var/log/mesos 

After that run Marathon in the same container:

/home/marathon-1.7.189-48bfd6000/bin/marathon --master 10.32.0.1:5050 --zk
zk://10.32.0.1:2181/marathon --hostname 10.32.0.1 --webui_url 10.32.0.1:8080
--logging_level debug

And finally, I run hadoop:

/opt/hadoop/sbin/start-dfs.sh

Marathon,Mesos and Hadoop are run without any problems. The most important
part of my work is running Flink in Marathon. I configured Flink in docker
container like this:

 env.java.home: /opt/java
  jobmanager.rpc.address: 10.32.0.1
  high-availability: zookeeper
  high-availability.storageDir: hdfs:///flink/ha/
  high-availability.zookeeper.quorum: 10.32.0.1:2181,10.32.0.2:2181
  recovery.zookeeper.path.mesos-workers: /mesos-workers

In Marathon UI, I create Application and put this JSON file on it, but it is
failed.

 {
  "id": "flink",
  "cmd": "/home/flink-1.7.0/bin/mesos-appmaster.sh 
   -Dmesos.master=10.32.0.1:5050,10.32.0.2:5050 
   -Dmesos.initial-tasks=1",
  "cpus": 1.0,
  "mem": 1024
   }

Flink application is failed in Mesos UI.
This is the error:

The strange thing is that in STDout, I see this text; even though I set
JAVA_HOME in /etc/environment and flink-conf.yam.

Please specify JAVA_HOME. Either in Flink config ./conf/flink-conf.yaml or
as system-wide JAVA_HOME.

Would you please tell me what I should do for that problem?

Many Thanks.
