HBase自定义过滤器（Filter）的问题

rzhzhz 2011-02-10 05:08:14

HBase中，添加其自带的过滤器不会出错，如SingleColumnValueFilter,PageFilter,但要添加自己的过滤器（防止出现代码错误，暂时把自定义过滤器的实现跟SingleColumnValueFilter一样）却总是报错，错误及代码如下，哪位高手能帮忙分析分析



Scan s = new Scan();

		Filter filter2 = new SingleColumnValueFilter("myColumFamily1".getBytes(),"myColum".getBytes(),CompareOp.NOT_EQUAL,"5".getBytes());

		Filter filter3 = new SingleColumnMatchValueFilter("myColumFamily1".getBytes(),"myColum".getBytes(),CompareOp.NOT_EQUAL,"5".getBytes());

		s.setFilter(filter3);

		ResultScanner ss = table2.getScanner(s);

		System.out.println();

		for(Result r:ss){

		    System.out.println(new String(r.getRow())+":"+r.getCellValues().length);

		    for(KeyValue kv:r.raw()){

		       System.out.println(kv.getKeyString()+"_______"+new String(kv.getValue()));

		    }

		}

错误
