## JIRA info

- Link: https://issues.apache.org/jira/browse/HUDI-8991
- Type: Sub-task
- Parent: https://issues.apache.org/jira/browse/HUDI-8695

Start with org.apache.hudi.utilities.TestHoodieMetadataTableValidator#testAdditionalPartitionsinMDT and review the referenced Azure CI failure. Reproduce the test repeatedly and trace why the filesystem and metadata-table partition listings differ. Done means the test no longer fails intermittently and continues to validate additional partitions correctly.
