我使用hadoopYarn配置文件安装并部署了giraph-1.1.0，命令如下

mvn -Phadoop_yarn -Dhadoop.version=2.6.0 -DskipTests clean package

从giraph examples/target文件夹中，我尝试运行shortestpathscomputation示例

hadoop jar giraph-examples-1.1.0-for-hadoop-2.6.0-jar-with-dependencies.jar \
org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimpleShortestPathsComputation \
-vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat \ 
-vip /user/$USER/input/testgraph.txt \
-vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat \
-op /user/$USER/output/shortestpaths -w 1 
-yj giraph-examples-1.1.0-for-hadoop-2.6.0-jar-with-dependencies.jar

运行时出现以下错误
error yarn.giraphyarclient:giraph:org.apache.giraph.examples.simpleshortestpathscomputation reports failed state，diagnostics show:application application\u 1471411023577\u 0001失败2次，原因是appattempt的am container\u 1471411023577\u 0001\u000002退出exitcode:-103 diagnostics:container[pid=30415，containerid=container\u 1471411023577\u 0001\u 02\u000001]运行超出虚拟内存限制。当前使用情况：使用273.2 mb的1 gb物理内存；使用了2.3 gb的2.1 gb虚拟内存。杀人容器。
我需要重建吉拉夫还是问题出在别处？
