--------------------------------------
Resolution: Duplicate
> Multi-table/Composite InputFormat example
> ------------------------------------------
>
> Key: ACCUMULO-1663
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1663
> Project: Accumulo
> Issue Type: Improvement
> Reporter: Corey J. Nolet
> Priority: Minor
> Labels: proposed
>
> For services that need to span more than a single table, it would be
> massively useful to either:
> 1) Provide a new input format capable to loading data from multiple tables or
> 2) Provide an example of extending/wrapping the current input format to
> provide such capability.
> It's not uncommon to have services that may span multiple tables and for each
> to require their own separate server-side iterators. Curent, in order to make
> this possible, the AccumuloInputFormat needs to be re-written. Adding the
> other table is really just a matter of running more scanners and generating
> the input splits for another table. It would be useful if the Accumulo core
> code base could provide some sort of composite or multi-table input format by
> default.
