我已经通过扩展 WritableByteArrayComparable 用于比较hbase中长值的类。这是代码供参考。

import org.apache.hadoop.hbase.filter.WritableByteArrayComparable;
import org.apache.hadoop.hbase.util.Bytes;

public class LongWritableComparable extends WritableByteArrayComparable {

public LongWritableComparable() {
    super();
}

public LongWritableComparable(byte[] value) {
    super(value);
}

public LongWritableComparable(Long value) {
    super(Bytes.toBytes(value));
}

@Override
public int compareTo(byte[] otherValue, int arg1, int arg2) {
    // TODO Auto-generated method stub
    byte[] thisValue = this.getValue();
    long thisLong = Bytes.toLong(thisValue);
    long otherLong = Bytes.toLong(otherValue,arg1,arg2);

    if (thisLong == otherLong) {
        return 0;
    }
    if (thisLong < otherLong) {
        return -1;
    }
    return 1;
  }

}

我在driver类中使用的比较器如下：

long endtimelongval = Long.valueOf(datetime.get("endDate").getMillis()).longValue();

LongWritableComparable etval=new LongWritableComparable(endtimelongval);

SingleColumnValueFilter eventCreationEndTimeFilter = new SingleColumnValueFilter(Bytes.toBytes("d"), Bytes.toBytes("et"), CompareOp.LESS,etval );

当我执行上述代码时，它抛出以下错误：

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.hadoop.hbase.filter.SingleColumnValueFilter.<init>([B[BLorg/apache/hadoop/hbase/filter/CompareFilter$CompareOp;Lorg/apache/hadoop/hbase/filter/WritableByteArrayComparable;)V

在 SingleColumnValueFilter 线路。
有人帮我解决吗。提前谢谢。
