我正在尝试运行giraph快速入门中描述的simpleshortestpathsvertex（又名simpleshortestpathscomputation）示例。我正在使用virtualbox在hortonworks沙盒示例（hdp2.1）上运行它，并使用profile hadoop\u2.0.0打包giraph.jar。
当我尝试使用
hadoop jar giraph.jar org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimpleShortestPathsVertex -vif
org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip
/user/hue/tinygraph.txt -of org.apache.giraph.io.formats.IdWithValueTextOutputFormat
-op /user/hue/output/shortestpaths -w 1我得到以下例外

at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:163)我找到了一个解决方法-看起来吉拉夫希望zookeeper在端口22181上运行，而实际上它在2181上运行。我只是使用ambari接口将zookeeper设置为在22181上运行（转到 http://127.0.0.1:8080/ ，登录admin/admin，服务选项卡，zookeeper并将端口更改为22181，保存和服务操作->全部重新启动。
有人有更好的解决这个问题的办法吗？是否有一个配置，通过它可以指定端口，或者giraph源代码中的这个端口是一个输入错误？

是的，您可以通过using选项指定每次运行giraph作业的时间
-Dgiraph.zkList=localhost:2181您还可以在hadoop配置中设置它，这样就不必每次提交giraph作业时都传递这个选项。为此，在conf/core-site.xml文件：<property><name>giraph.zkList</name><value>localhost:2181</value></property>[请检查语法，我不记得它在我的头上，目前我没有访问群集来检查它]
