Start by running RemoteLogScannerITCase.testPartitionTableFetchFromRemote and compare the failure with the linked GitHub Actions run. Trace the FetchException through CompletedFetch.java, LogFetchCollector.java, AbstractLogFetchCollector.java, and ClientToServerITCaseBase.java. Done means the integration test passes reliably without the reported remote partition-table fetch failure.
