@If you are facing the following error, you should change version 2.1 on the common.io.

Hbase - anything else on the Scan

// Hbase
BinaryComparator comparator = new BinaryComparator(Bytes.toBytes("key"));
Filter filter = new RowFilter(CompareOp.EQUAL, comparator);
// Mysql
[select * from aTable where ROW='key']

// Hbase
byte[] prefix = Bytes.toBytes("key");
Filter filter = new PrefixFilter(prefix);
// Mysql
[select * from aTable where ROW like'key%']

// Hbase
byte[] stop = Bytes.toBytes("key");
Filter filter = new InclusiveStopFilter(stop);
// Mysql
[select * from aTable where ROW<='key']

Hbase - Page limit

@For a paging like [Select * from aTable limit 10]

// HbaseDao.java
    public ResultScanner resultScanner(String tableName, int intPages) throws Exception {

        // Get a object from Pool
        HTableInterface hTable =  htablePool.getTable(tableName);

        long pageSize = intPages;
        Filter filter = new PageFilter(pageSize);
        Scan s =new Scan();
        s.setFilter(filter);

        ResultScanner rs = hTable.getScanner(s);

        return rs;
    }
