>          Issue Type: Bug
>    Affects Versions: 0.90.4

> The scanner used for compaction doesn't limit the number of columns retrieved when doing a compaction. If a row exists with tens of millions of rows it can fill all available memory and crash the region server. 
> It would be better if the scanner could page through the columns of wide rows when performing a compaction.
