Thanks J-D,
but i check the source, in HRegion.delete, there are some codes like this:
public void delete(){
...
prepareDelete(delete); // here will check if Delete has no columnfamily,
it will reset it's all columnFamilies.
internalDelete(...); // Coprocessor.preDelete triggered here
...
}
As the codes shows here, the 'no columns are specified' Delete will be
modifid to 'full columns specified' Delete before Cp.preDelete triggered.
So i stll get no way to find out if a Delete is going to delete a full
row...
