            Why not just run N rowcounter MR jobs?

            My plan is to accept regex as table names and use MetaScanner.metaScan() to discover the tables.
            The goal is to calculate the total number of rows across all those tables.

            I came upon this requirement when investigating HBASE-2885.

            TableInputFormatBase in both namespaces only keeps reference to HTable.
            An HTable array needs to be used for this request.
