Subject Re: Flink CLI cannot submit job to Flink on Mesos
Date Tue, 01 Aug 2017 09:36:34 GMT
Hey! It´s working now!!

I will do a summary for those who might have the same problem in the future:

- Flink 1.3.0 dockerized on Mesos:
- Add the HA configuration values in your flink app: https://ci.apache.org/projects/flink/flink-docs-release-1.3/setup/jobmanager_high_availability.html#config-file-flink-confyaml
- Add the Mesos HA configuration values in your flink app: https://ci.apache.org/projects/flink/flink-docs-release-1.3/setup/mesos.html#high-availability

- Flink CLI 1.3.0 on my local machine (make sure you use the same version!!)
- Add same HA configuration values in your flink CLI configuration: https://ci.apache.org/projects/flink/flink-docs-release-1.3/setup/jobmanager_high_availability.html#config-file-flink-confyaml


With those steps, my ./fink run command it´s working like a charm.

Thank you very much guys!

Regards,
Francisco

Hi Stephan,

So, do you mean to remove the “-m” param from the flink CLI call? And on the other hand,
that I should add the Zookeeper configuration in both sides, the remote flink and locally
in the flink CLI config, right?

Regards

Hi Francisco!

Can you drop the explicit address of the jobmanager? The client should pick up that address
automatically from ZooKeeper as well (together with the HA leader session ID).

Please check if you have the ZooKeeper HA config entries in the config used by the CLI.

Hi again,

On the other hand, we are running the following flink CLI command:

./flink run -d -m ${jobmanager.rpc.address}:${jobmanager.rpc.port}  ${our-program-jar} ${our-program-params}

Maybe is the command what we are using wrongly?

Thank you

Hi Francisco,

have you set the right high-availability configuration options in your client configuration
as described here [1]? If not, then Flink is not able to find the correct JobManager because
it retrieves the address as well as a fencing token (called leader session id) from the HA
store (ZooKeeper).

Cheers,

Hello,

We´re having lot of issues while trying to submit a job remotely using the Flink CLI command
line tool. We have tried different configurations but in all of them we get errors from AKKA
while trying to connect. I will try to summarise the configurations we´ve tried.

- Flink 1.3.0 deployed within a docker container on a Mesos cluster (using Marathon)
- This flink has the property jobmanager.rpc.address as a hostname (i.e. kind of ip-XXXXXXXXX.eu<http://ip-xxxxxxxxx.eu/>.west-1.compute.internal)
- Use the same version for Flink Client remotely (e.g. in my laptop).

When I try to submit the job using the command flink run -m myHostName:myPort (the same in
jobmanager.rpc.address and jobmanager.rpc.port) after some time waiting I get the trace at
the end of this email. In the flink side we get this error from AKKA:

Association with remote system [akka.tcp://flink@10.203.23.24:24469] has failed, address is
now gated for [5000] ms. Reason: [Association failed with [akka.tcp://flink@10.203.23.24:24469]]
Caused by: [Connection refused: /10.203.23.24:24469<http://10.203.23.24:24469/>]

After reading a bit, it seems there´re some problems related to akka resolving hostnames
to ips, so we decided to startup the same flink but changing jobmanager.rpc.address to have
the direct ip (i.e. kind of XX.XXX.XX.XX). In this case I´m getting same trace (at the end
of the email) from the client side and this one from the Flink server:

Discard message LeaderSessionMessage(00000000-0000-0000-0000-000000000000,SubmitJob(JobGraph(jobId:
b25d5c5ced962632abc5ee9ef867792e),DETACHED)) because the expected leader session ID b4f53899-5d70-467e-8e9d-e56eeb60b6e3
did not equal the received leader session ID 00000000-0000-0000-0000-000000000000.

We have tried some other stuff but without success… any clue that could help us?

Thanks in advance!
