Summary: [DiskBalancer] Validate persisted diskbalancer.info while
reading YAML
Key: HDDS-15438
URL: https://issues.apache.org/jira/browse/HDDS-15438
Project: Apache Ozone
Issue Type: Improvement
Reporter: Shilun Fan
Assignee: Shilun Fan
DiskBalancerYaml.readDiskBalancerInfoFile() currently accepts some malformed
diskbalancer.info content without failing at the YAML read boundary. For
example, missing operationalState, missing or unsupported version, or invalid
persisted configuration values can be read into DiskBalancerInfo and only fail
later during service initialization, status/report generation, or persistence.
This makes startup failures harder to diagnose and can leave DiskBalancer with
partially invalid in-memory state. The YAML reader should validate persisted
data immediately and fail with a clear IOException.
