Description

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:

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
