Anoop Sam John commented on HBASE-6132:
---------------------------------------

[~saint.ack@gmail.com]  Can you please see the attached test case once. Using HRegion directly.
Owners of Filter- can some one pls tell the reason for code in FilterList#filterRow() using
filterAllRemaining()

> 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}
