I checked with updated translator that I built from the upstream branch. The issue seems to be resolved by the fix.

> Accumulo doesn't return null values when a whole 'column' is being selected.
> For a command in accumulo shell like:
> {code:plain}
> scan -c name:BYTENUM
> {code}
> Accumulo returns only non-empty values, this is expected behaviour.
> Equivalent query in Teiid would be:
> {code:sql}
> SELECT ByteNum FROM SmallA
> {code}
> Which returns the same results as Accumulo does. That means, no NULL values, if there are rowids without specified column families/qualifiers missing. But when a user has his schema defined in a vdb, he probably expects, that he will get as many rows as there are in the table.
