今天写了一段简单的java代码调用Hbase的API，代码如下：

public class HbaseApi {
	private HTable hTable ;
	private String tableName;
	public HbaseApi(String tableName) throws IOException {
		this.tableName = tableName;
		HBaseConfiguration hconfig = new HBaseConfiguration();
		hconfig.set("hbase.zookeeper.property.clientPort","2181");
		hconfig.set("hbase.zookeeper.quorum", "192.168.179.130");  
		hTable = new HTable(hconfig, this.tableName.getBytes());
	}
	
	public void scan(String family, String qualifier) throws IOException {
		Scan scan = new Scan();
		scan.addColumn(family.getBytes(), qualifier.getBytes());
		
		ResultScanner scanner = hTable.getScanner(scan);
		
		for(Result result = scanner.next(); result != null; result = scanner.next() ) {
		}
	}
	
	public static void main(String[] args) {
		try {
			new HbaseApi("teacher").scan("teacher", "info");;
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	
}

执行的时候出现错误：从错误上看，应该是Hbase的一个类重载了protobuf-java的一个final方法导致的。我使用hadoop的版本是2.2.0， Hbase版本是0.96，protobuf的版本是2.5.如有大神遇到相同的问题，请提供以下解决方法，再此谢过
