Hi Stefan,

Thanks a lot for your answer and sharing the link https://github.com/mesoshq/flink. I went through this and saw its spawning Jobmanager and taskmanager. Now I think, this should be happening. First JobManager will be started on flink cluster on one node, then task manager will be started on another node and both should be running in docker containers on different nodes. Now, my question is how flink's JobManager will get to know about the taskManagers as they are in in different docker containers on different nodes? Will it happen via Mesos?

Can we use mesos-appmaster.sh instead which is already built in flink for deployment on mesos?

Hi,

as in my answer to your previous mail, I suggest to take a look at https://github.com/mesoshq/flink . Unfortunately, there is not yet a lot documentation about the internals of how this works, so I am also looping in Till who might know more about specific questions about how things work together exactly.

Best,

Stefan

Currently I have a Flink Application Jar file running on Mesos cluster. The flink application simply reads data from Kafka and put it to HDFS.

Now we are planning to create a docker image to  run this application jar file inside docker containers on Mesos cluster via Marathon. 

Below are the questions that I am looking answers for:

1. While building the docker image, how do I include flink-1.3.2 set up and  my mesos config in flink?

2. How shall I run my existing flink application jar?

3. Will running my flink application jar on docker containers will run it on mesos slaves on different docker containers? How docker , Flink, mesos , Marathon will work together in my case?
