> Log a warning if multiple versions of a Compaction Workers are running
> compactions.
> The start time of the individual HMS services are not stored at the moment,
> however this information could proved a good baseline of detecting multiple
> Worker versions.
> Due to the lack of this information we can check periodically in the past N
> hours to detect the versions.
> The N hours can be configured by
> {{metastore.compactor.worker.detect_multiple_versions.threshold}} property.
> This periodical check only make sense if the Compaction are enabled.
