我正在尝试从java开始mapreduce工作。但当我试图提交我得到的工作 Permission Denied
例外。我能跑了 hdfs dfs -ls /
从命令行没有任何错误。但是我的java程序不能运行。
这是我的密码
public static void main(String[] args) {
Configuration conf=new Configuration();
conf.set("mapreduce.map.class","org.apache.hadoop.conf.TestMapper");
conf.set("mapreduce.reduce.class","org.apache.hadoop.conf.TestReducer");
conf.set("mapreduce.framework.name","yarn");
conf.set("hadoop.security.group.mapping","org.apache.hadoop.security.ShellBasedUnixGroupsMapping");
conf.set("fs.default.name","hdfs://master:9000");
conf.set("dfs.permission","false");
conf.set("yarn.nodemanager.aux-services","mapreduce_shuffle");
conf.set("yarn.resourcemanager.resource-tracker.address","master:8025");
conf.set("yarn.resourcemanager.scheduler.address","master:8030");
conf.set("yarn.resourcemanager.address","master:8040");
conf.set("yarn.nodemanager.localizer.address","master:8060");
Job job=null;
try {
job = Job.getInstance(conf, "Test Map Reduce");
job.setJarByClass(RunJob.class);
job.setOutputKeyClass(LongWritable.class);
job.setOutputValueClass(Text.class);
job.setInputFormatClass(TextInputFormat.class);
job.setOutputFormatClass(TextOutputFormat.class);
TextInputFormat.setInputPaths(job, new Path("/input.txt"));
TextOutputFormat.setOutputPath(job, new Path("/output"));
job.submit();
}
但我有以下例外
org.apache.hadoop.security.AccessControlException: Permission denied: user=manthosh, access=EXECUTE, inode="/tmp":hduser:supergroup:drwxrwx---
这里的解决方案行不通。
我错过了什么?
