我试图从 Eclipse 运行 SSSP giraph 程序。但我无法导入以下包
import org.apache.giraph.graph.BasicVertex;
import org.apache.giraph.graph.BspUtils;
import org.apache.giraph.graph.GiraphJob;
import org.apache.giraph.graph.EdgeListVertex;
import org.apache.giraph.graph.VertexReader;
import org.apache.giraph.graph.VertexWriter;
import org.apache.giraph.lib.TextVertexInputFormat;
import org.apache.giraph.lib.TextVertexInputFormat.TextVertexReader;
import org.apache.giraph.lib.TextVertexOutputFormat;
import org.apache.giraph.lib.TextVertexOutputFormat.TextVertexWriter;
我已按照 giraph 站点中的说明构建 Giraph 和 Hadoop。应该导入哪个jar来获取上面的包?
