Josh Elser resolved ACCUMULO-1014.
----------------------------------
       Resolution: Won't Fix
    Fix Version/s:     (was: 1.7.0)

Integration already exists with Pig and Hive. For now, let's table this, encourage adoption of these integrations and re-evaluate if there is still some deficiency these don't provide.

>             Project: Accumulo
>          Issue Type: Wish

> Implement a query language.
> We can do some basic selection/projection and roll-up using iterators.
> I'm thinking something like:
> {noformat}
> using LatLonRow;
> SELECT * 
>  WHERE row MATCHES LatLonRow.ranges('0.0', '0.0', '0.25', '0.25')
>    AND columnFamily == 'mapLevel2'
> ;
> {noformat}
> Given a table structure, we can support the expressiveness of JEXL and the wikisearch example.
> {noformat}
> using ShardDocument;
> SELECT ShardDocument.document(row)
>  WHERE row MATCHES ShardDocument.ranges('1990-01-01', '2012-11-10')
>    AND ShardDocument.jexl(
>      'author ~= ".*Adams" and body = "don't" and body = 'panic'
>       );
> {noformat}
> I'm sure the syntax is highly suspect, but abuse of the index as well as the indexing structure ought to be something expressible to mere mortals.
