Windows平台開發Mapreduce程式遠程調用運行在Hadoop叢集—Yarn調度引擎異常

標籤：roc   snapshot   create   inpu   nat   ext   too   調度   nod   

共用原因：雖然用一篇博文寫問題感覺有點奢侈，但是搜尋百度，相關文章太少了，苦苦探尋日誌才找到解決方案。

遇到問題：在windows平台上開發的mapreduce程式，運行遲遲沒有結果。

Mapreduce程式

public class Test {    public static void main(String [] args) throws Exception{        Configuration conf = new Configuration();       conf.set("fs.defaultFS", "hdfs://master:9000/");        conf.set("mapreduce.job.jar", "D:/intelij-workspace/aaron-bigdata/aaorn-mapreduce/target/aaorn-mapreduce-1.0-SNAPSHOT.jar".trim());        conf.set("mapreduce.framework.name", "yarn");        conf.set("yarn.resourcemanager.hostname", "master");        conf.set("mapreduce.app-submission.cross-platform", "true");        Job job = Job.getInstance(conf);        job.setMapperClass(WordCountMapper.class);        job.setReducerClass(WordCountReducer.class);        job.setMapOutputKeyClass(Text.class);        job.setMapOutputValueClass(LongWritable.class);        job.setOutputKeyClass(Text.class);        job.setOutputValueClass(LongWritable.class);        FileInputFormat.setInputPaths(job,"hdfs://master:9000/input/");        FileOutputFormat.setOutputPath(job,new Path("hdfs://master:9000/output3/"));        job.waitForCompletion(true);    }}

  說明我的hadoop叢集是Master(namenode)、Slave1、Slave2、Slave3  解決辦法在所有的Slave機器的yarn-site.xml,之前我只在Master機器上添加了這些內容
