Question

我在AWS上运行最短路径示例时遇到问题。我通过S3下载了giraph jar（在我使用和上传的同一个AMI中编译），在master和slave中正确配置了zookeper，我做了以下步骤：

nano /tmp/tiny_graph.txt

[0,0，[1,1,3,3]] [1,0，[0,1,2,2,3,1]] [2,0，[1,2,4,4]] [3,0，[0,3,1,1,4,4]] [4,0，[3,4,2,4]]
hdfs dfs -mkdir / user / hduser
/ home / hadoop / bin / hdfs dfs -copyFromLocal /tmp/tiny_graph.txt /user/tiny_graph.txt
hdfs dfs -mkdir / user / hduser / output
/ home / hadoop / bin / yarn jar /home/hadoop/share/hadoop/yarn/lib/giraph.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimpleShortestPathsComputation -vif org .apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip /user/hduser/input/tiny_graph.txt -vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op / user / hduser / output / shortestpaths -w 2

控制台告诉我这个，我不知道发生了什么：

任何帮助都会有很大帮助！

当我停止在AWS上使用MapR时，我解决了这个问题。出于某种原因 Giraph 和 MapR 不相处。

最短路径 - Giraph示例 - 不在AWS上工作
