> Dru Jensen wrote on hbase-user@
> > I found what is causing the same rows being sent to multiple map tasks.
> > If you have the same column family name in other tables, the Test will
> > send the same rows to multiple map reducers.
> Stack wrote in response:
> > Indeed, a bug in getStartKeys will make us process all tables that have
> > a column family name in common.
> [...]
> > The above Visitor is visiting the meta table.  Its checking column
> > family name.  Any region that is not offlined or split gets added to the
> > list of regions.  Its not checking that the region belongs to the wanted
> > table.
