SingleColumnValueFilter for empty column qualifier
Jonathan Bishop 2012-10-31, 21:49

I am trying to use SingleColumnValueFilter to find only those rows which
have a particular column which is empty. Not sure what to use for the value
(4th arg in const). It does not take null, and I tried something like...

byte[] v = new byte[0];

but that does not seem to work.
