Jacques Nadeau updated DRILL-626:
---------------------------------
Description:
If a query against an HBase table requires only a subset of columns, we should
qualify the HBase scan with these columns.
For example
{noformat}
SELECT row_key, f['c1'], f['c2'], g FROM hbase.MyTable
{noformat}
should qualify he HBase scan as {{families => \[g\["ALL"], f\["c1", "c2"]]}}
> Project push down into HBase scan
