使用Giraph运行自带的SimpleShortestPaths，出现个错误，一直未解决：

点进：http://hadoop102:8088/cluster/app/application_1599991661751_0001去看，提示如图： 明明肯定是存在GiraphApplicationMaster类的。但是就是报错。 然后我用命令：
cp $GIRAPH_HOME/giraph-examples/target/giraph-examples-1.1.0-for-hadoop-2.6.0-jar-with-dependencies.jar $HADOOP_HOME/share/hadoop/yarn/lib/问题得到解决。供大家参考！！
