我正在尝试使用最新的Giraph代码和Hadoop 2.5.2运行SimpleShortestPathsComputation示例。我的命令行如下:
hadoop jar /home/prhodes/giraph/giraph-examples/target/giraph-examples-1.2.0-SNAPSHOT-for-hadoop-2.5.2-jar-with-dependencies.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimpleShortestPathsComputation -vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip /user/prhodes/input/tiny_graph.txt -vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op /user/prhodes/giraph_output/shortestpaths -w 4
工作似乎开始得不错。但接着它开始输出这些类型的信息,而且这只会继续下去(看起来)直到你使用ctrl+c停止。

你知道这里发生了什么吗?
