	Get get = new Get(
			Bytes.toBytes("{1F591795-74DE-EB70-0245-0E4465C72CFA}"));
	get.addColumn(Bytes.toBytes("bhvr"), Bytes.toBytes("vvmid"));
	get.setMaxVersions(100);
	// get.setTimeRange(1354010844711L - 12000L, 1354010844711L);

	// get.setTimeStamp(1354700700000L);

	Filter filter = new ColumnPaginationFilter(1, 10);
	get.setFilter(filter);

	Result dbResult = table.get(get);

	System.out.println("result=" + dbResult.toString());

	long en2 = System.currentTimeMillis();
	System.out.println("Total Time: " + (en2 - st) + " ms");
