If 'firstName' is NULL - it is missing completely from a row. Add explicitly this column to Scan you create:

Subject: filtering rows for column values not null
Hi I have a relatively simple situation,
As an example I have a table of Users, with first and last name.
I set a scan a FilterList and I add a SingleColumnValueFilter, with
column qualifier=firstName, CompareOp.EQUAL, and value="bob".
The problem is, I'm getting "bob" as well as anyone with out a firstName.
I tried adding NOT_EQUALS null and NOT_EQUALS (new byte) and neither helped.
Does anyone know of how to filter on a column value not null?
