> Add optional FedBalance content summary verification
> ----------------------------------------------------
>
> Key: HDFS-17949
> URL: https://issues.apache.org/jira/browse/HDFS-17949
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: QI, Jiale
> Priority: Major
> Labels: pull-request-available
>
> FedBalance currently finishes after the final DistCp succeeds, but it does
> not provide an optional built-in verification step to compare the source and
> destination tree at a coarse content-summary level.
> This issue proposes adding an optional FedBalance verification phase after
> the final DistCp succeeds. The verification is disabled by default and can be
> enabled through CLI or configuration. When enabled, it compares the source
> and destination ContentSummary directory count, file count, and length after
> excluding snapshot content.
> This gives operators a lightweight built-in correctness check without
> changing the default FedBalance behavior.
> Proposed changes:
> - Add an optional VERIFY stage to DistCpProcedure.
> - Add a FedBalanceVerifier helper based on ContentSummary.
> - Add a CLI option and configuration key to enable verification.
> - Add tests for successful verification and mismatch detection.
