Sorry for the flood of e-mails... I'm not trying to spam the list, I'm just getting deeper into accumulo, and loving it, and I'm kind of stumped by it at the same time.
Is it true that if a scanner restricts the column families/qualifiers to be returned, that these columns are not visible to any iterators? ie. that this restriction is applied at a higher "priority" than any of the iterators?
I have a couple of RowFilters chained together to filter based on source and filename. If I just run "scan --columns meta:size" I get no results. I have to specify "scan --columns meta:size,meta:source,meta:filename" to get any results, which implies that I need to know beforehand which columns are required for any active iterators.

The decisionIterator that the RowFilter uses to determine if a row should be accepted could be seeked to different columns than the RowFilter itself is provided. However, the default implementation of RowFilter does not do this. There might be a fairly straightforward change that could be made to RowFilter that would allow its subclasses to customize the columns passed to the decisionIterator.
