似乎远程运行作业时，yarn.application.classpath必须在配置中，否则作业将失败

要运行此作业，请使用此配置

Configuration configuration = new Configuration();
configuration.set(“fs.defaultFS”, “hdfs://192.168.195.161:8020″);
configuration.set(“hadoop.job.ugi”, “root”);
configuration.set(“mapreduce.framework.name”, “yarn”);
configuration.set(“yarn.resourcemanager.address”a “192.168.195.161:8050″);
configuration.set(“yarn.nodemanager.aux-services”, “mapreduce_shuffle”);

final String[] args = new String[] { };
ToolRunner.run(configuration, jobDriver, args);
