Subject Re: Flink CLI cannot submit job to Flink on Mesos
Date Mon, 31 Jul 2017 20:21:27 GMT
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.

Stephan
