> *Description*
> When deploying a Flink session on YARN, the {{DispatcherRestEndpoint}} may incorrectly
bind on a local address. When this happens, the job submission and all REST API calls using
a non-local address will fail. Setting {{rest.address: 0.0.0.0}} in {{flink-conf.yaml}} has
no effect because the value is overridden.
