> Add FedBalance operational control switches
> -------------------------------------------
>
> Key: HDFS-17950
> URL: https://issues.apache.org/jira/browse/HDFS-17950
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: QI, Jiale
> Priority: Major
>
> Large FedBalance jobs may need operator-controlled stop and resume points,
> especially around the initial copy, incremental copy, and final cutover
> window.
> This issue proposes adding optional operational control switches for
> FedBalance. All new controls are disabled by default and do not change the
> existing default behavior.
> Proposed controls:
> - Stop after the initial DistCp succeeds.
> - Start a later job from the incremental DistCp stage after validating the
> required prior-copy state.
> - Stop instead of retrying forever when the diff is small enough but
> final-copy conditions are blocked by open files.
> - Gate leaving the incremental DistCp stage on a time-window sentinel path.
> - Allow a sentinel path to make open files force-closeable.
> These controls make long-running FedBalance migrations easier to operate
> while preserving the current default behavior.
