--------------------------------------
Summary: BindException in TestSCMRestart
Key: HDDS-2863
URL: https://issues.apache.org/jira/browse/HDDS-2863
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Recon, SCM
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
Recon exposes SCM-like RPC endpoints on (possibly) different port than SCM.
However, when the RPC updates the config with the actual address after startup,
it does so using the SCM-specific config key. Now that Recon is part of
{{MiniOzoneCluster}}, this causes BindException in {{TestSCMRestart}} (and
possibly other integration tests):
