[jira] [Closed] (FLINK-25269) Return 503 Service Unavailable if endpoint is not ready yet
[ https://issues.apache.org/jira/browse/FLINK-25269?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chesnay Schepler closed FLINK-25269.
------------------------------------
Fix Version/s: 1.16.0
Release Note: The REST API now returns a 503 Service Unavailable error when a request is made but the backing component isn't ready yet. Previously this returned a 500 Internal Server error.
Resolution: Fixed
master: d67338a140bf1b744d95a514b82824bba5b16105

> If an endpoint (e.g., the RM) has not been started yet when receiving a request from the REST API, then an exception is thrown that is treated as an unhandled exception. we can handle this in a nicer way by returning 503 Service Unavailable.
