我正在使用一个虚拟机，拥有一个由1个主节点和3个节点组成的集群，我安装了hadoop并将其复制到所有节点，并在主节点中部署giraph，但我不知道是否也应该将giraph文件夹复制到所有节点！！，我使用的是真正的数据集wikitalk，我的命令行是
$hadoop\u home/bin/hadoop jar$giraph\u home/giraph examples/target/giraph-examples-1.3.0-snapshot-for-hadoop-2.5.1-jar-with-dependencies.jar org.apache.giraph.giraphrunner org.apache.giraph.examples.simplepagerankcomputation-vif org.apache.giraph.io.formats.jsonlongtublefloatdoublevertexinputformat-vip/user/hduser/input/wikitalk.txt-voforg.apache.giraph.io.formats.idwithvaluetextoutputformat-op/user/hduser/output/wikitalk11\u output-w 4
但我发现了这个例外

所以我不知道这个例外的原因是什么？！！
