Date Wed, 07 Mar 2018 16:40:00 GMT
Gary Yao created FLINK-8891:
-------------------------------

             Summary: RestServerEndpoint can bind on local address only
                 Key: FLINK-8891
                 URL: https://issues.apache.org/jira/browse/FLINK-8891
             Project: Flink
          Issue Type: Bug
          Components: REST, YARN
    Affects Versions: 1.5.0
         Environment: EC2 AMI debian-jessie-amd64-hvm-2017-01-15-1221-ebs (ami-5900cc36)
Hadoop 2.8.3
Flink commit 80020cb5866c8bac67a48f89aa481de7de262f83
            Reporter: Gary Yao
             Fix For: 1.5.0


*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.
