我有一個名爲WordCountMain.jar
的jar。我想在多模式集羣中使用hadoop命令運行此jar。Mapreduce隊列設置
但我的用戶ID被標記爲排隊名稱爲「歐米茄」。所以如果我使用下面的命令運行上面的jar,那麼我得到一個錯誤,表明我的id沒有submit_job訪問權限。在多模集羣
hadoop jar WordCountMain.jar /user/cloudera/inputs/words.txt /user/cloudera/output
所以上面的命令沒有工作,但它在單節點集羣CDH3工作
我如何包括隊列名,而在運行上面的jar?
Configuration conf = new Configuration();
Job job = new Job(conf,"word count");
job.getConfiguration().set("mapreduce.job.queuename","omega");
job.setJarByClass(WordCountCombinerMain.class);
Path inputFilePath = new Path(args[0]);
Path outputFilePath = new Path(args[1]);
FileInputFormat.addInputPath(job, inputFilePath);
FileOutputFormat.setOutputPath(job, outputFilePath);
job.setInputFormatClass(TextInputFormat.class);
job.setOutputFormatClass(TextOutputFormat.class);
job.setMapperClass(CWordCountMapper.class);
job.setCombinerClass(CWordCountCombiner1.class);
job.setReducerClass(CWordCountCombiner1.class);
//job.setReducerClass(CwordCountReducer.class);
job.setMapOutputKeyClass(Text.class);
job.setMapOutputValueClass(IntWritable.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(IntWritable.class);
job.waitForCompletion(true);
job.submit();
但是我得到了下面的錯誤。這個錯誤說,我的MapReduce工作就是讓在默認隊列提交..有人可以幫助我在此
