-------------------------------------

             Summary: jobmanager.rpc.addresss does not support hostname with an underscore
                 Key: FLINK-22977
                 URL: https://issues.apache.org/jira/browse/FLINK-22977
             Project: Flink
          Issue Type: Bug
            Reporter: Nikesh Hajari


Using Docker to setup a Flink job manager - when the jobmanager.rpc.address has an underscore in the hostname  - the error message below is received. I have included a working and non-working sample below by only changing one "dash" to an "underscore".

2021-06-14 02:25:48,485 WARN org.apache.flink.runtime.webmonitor.retriever.impl.RpcGatewayRetriever [] - Error while retrieving the leader gateway. Retrying to connect to akka.tcp://flink@lsp-dev-apache_flink-job-manager:6123/user/rpc/dispatcher_*.

From Web UI: \{"errors":["Service temporarily unavailable due to an ongoing leader election. Please refresh."]}

 

*This works - RPC without underscore*

*This does not work - RPC with underscore*
