Is it possible to imply filter on two resultset in hbase;

Suppose I have following scenario:

        Get get1 = new Get(Bytes.toBytes("row-5"));
        get1.setFilter(filter1);
        Result result1 = table.get(get1); 
        System.out.println("Result of get(): " + result1);

        Filter filter2 = new FamilyFilter(CompareFilter.CompareOp.EQUAL,
          new BinaryComparator(Bytes.toBytes("colfam3")));
        Get get2 = new Get(Bytes.toBytes("row-5")); 
        get2.addFamily(Bytes.toBytes("colfam1"));
        get2.setFilter(filter2);
        Result result2 = table.get(get2); 
        System.out.println("Result of get(): " + result2);

So now I have two result sets, result1 and result2. What should be approach to put union on these result sets to remove duplicates?

There is no canned method to do this. You can grab the NavigableMap from the Result and put that into a TreeMap and use putAll to merge the maps.

It's probably better to just create a FilterList with all the Filters you want before you do the Get or Scan.
