hbase的Ｓcan中的setBatch方法和setFilter方法的冲突_为什么不能一起用呢???

在setＦilter方法后调用setBatch方法直接抛出异常
源代码如下:

 public Scan setBatch(int batch) {

    if (this.hasFilter() && this.filter.hasFilterRow()) {

      throw new IncompatibleFilterException(

        "Cannot set batch on a scan using a filter" +

        " that returns true for filter.hasFilterRow");

    }

    this.batch = batch;

    return this;

  }

如果在setBatch方法后调用setＦilter方法设置Ｆilter Ｈbase服务器将抛出异常
