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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
