>
> getclosestatorbefore was not converted to deal with the new delete types. It
> only knows how to process old style deletes. Usually all is well as edits
> come in but its possible to get into state where you have persisted in one
> file a deletefamily for all in meta and in the file behind it, there are
> entries on the info family. Since closest doesn't understand deletefamily,
> it will return the Put rows only for the subsequent getfull, which knows how
> to work with deletefamilies fail.
> Once this happens, table is hosed. Seen on Bradford Stephens upload and at
> Powerset. "Fix" is flush and major compact. Gives impression that hbase is
> 'delicate'. Fixing.
