andyhuangdev opened a new pull request, #11789: URL: https://github.com/apache/ozone/pull/11789
## What changes were proposed in this pull request? Long-lived Ozone clients, including S3 Gateway, cache the OM version at startup. After ZDU finalization, they continue using the old version and keep newly available features disabled until restarted. This change refreshes the cached OM version through service info when first accessed after a 10-minute expiry. Concurrent callers share one refresh. If the refresh fails, the client retains the last known version and waits another 10 minutes before retrying. Client feature checks and newly created output streams use the refreshed version. Existing streams retain their captured version. Refreshes run on the calling thread, preserving S3 authentication context without background polling or server-side changes. ## What is the link to the Apache JIRA [HDDS-17140](https://issues.apache.org/jira/browse/HDDS-17140) ## How was this patch tested? - Added three regression tests and confirmed they failed before the fix. - Added coverage for concurrent refreshes and propagation of the calling thread’s S3 credentials. - TestRpcClient: all 185 tests passed. - ./hadoop-ozone/dev-support/checks/checkstyle.sh: passed. - git diff --check: passed. -- This is an automated message from the Apache Git Service.
