ClassNotFoundException在修改后的SimpleShortestPathsVertex上运行GiraphRunner

我对Giraph比较陌生，我正在努力让我的Giraph edit-compile-deploy循环适用于我们的代码。 我能够运行各种灵感来自http://blog.cloudera.com/blog/2014/02/how-to-write-and-run-giraph-jobs-on-hadoop/的例子，但我坚持不懈运行我的SimpleShortestPathsVertex Giraph示例的修改版本时出现ClassNotFoundException。 我已经尝试过-libjars和HADOOP_CLASSPATH的各种组合，但我没有想法，我真的很感谢你的帮助。 细节如下。 版本 Hadoop：Hadoop 2.0.0-cdh4.4.0 Giraph：giraph-examples-1.0.0-for-hadoop-2.0.0-alpha-jar-with-dependencies.jar PageRankBenchmark运行正常 $ hadoop jar $GIRAPH_HOME/giraph-examples/target/giraph-examples-1.0.0-for-hadoop-2.0.0-alpha-jar-with-dependencies.jar \ org.apache.giraph.benchmark.PageRankBenchmark \ -Dgiraph.zkList=:2181 \ -e 1 -s 3 -v -V 50 -w 1 … 14/08/01 11:42:44 INFO mapred.JobClient: Job complete: job_201407291058_0015 … (full output is below) GiraphRunner SimpleShortestPathsVertex也运行正常 $ hadoop jar $GIRAPH_HOME/giraph-examples/target/giraph-examples-1.0.0-for-hadoop-2.0.0-alpha-jar-with-dependencies.jar \ org.apache.giraph.GiraphRunner \ -Dgiraph.zkList=:2181 \ org.apache.giraph.examples.SimpleShortestPathsVertex \ […]
