> IndexRebuildRegionScanner is the server side engine to rebuild and verify
> every index row pointed by the data table. IndexRebuildRegionScanner runs on
> data table regions and scans every data table rows locally, and then rebuilds
> and verifies index table rows referenced by the data table rows over
> server-to-server RPCs using the HBase client installed on region servers.
> However, IndexRebuildRegionScanner cannot clean up the index rows that are
> not referenced by the data table if there are such index rows. In order to do
> that we need another region scanner that scans index table regions and makes
> sure that every index row is valid. This region scanner will be called
> IndexRepairRegionScanner.
