我曾经使用（使用GenericOptionsParser）运行hadoop mapreduce
hadoop jar app.jar app -files /home/some/file#file
然而，在最近版本的hadoop中我得到了
Hadoop command-line option parsing not performed. Implement the Tool interface and execute your application with ToolRunner to remedy this.
那么如何使用ToolRunner实现-files选项在所有mapreduce节点之间共享？
答案 0 :(得分：0)
显然以前的已被弃用......
这就是我做的......
import org.apache.hadoop.conf.Configuration;
.
.
.
Configuration conf = new Configuration();
.
Job job = Job.getInstance(conf, "appname");
job.setJarByClass(appname.class);
.
.
job.addCacheFile(new URI("/file/in/hdfs/APP/appfile#appfile"));
.
