>
> Thanks to Anoop and Ramkrishna, here's what we found with FilterList
> If I use FilterList to include ColumnCountGetFilter among other filters, the returning
Result has no keyvalues.
> This problem seems to occur when specified column count is less then actual number of
existing columns.
> Also same problem arises with PageFilter
> Following is the code of the problem:
> {code}
> Configuration conf = HBaseConfiguration.create();
> HTable table = new HTable(conf, "test");
> Get get = new Get(Bytes.toBytes("test00001"));
> FilterList filterList = new FilterList();
> filterList.addFilter(new ColumnCountGetFilter(100));           
> get.setFilter(filterList);
> Result r = table.get(get);
> System.out.println(r.size()); // prints zero
> {code}
