      Description

      When you see a stack trace about permissions, it is better if the trace included the file/directory at fault:

      Exception in thread "main" java.io.IOException: Permission denied
      	at java.io.UnixFileSystem.createFileExclusively(Native Method)
      	at java.io.File.checkAndCreate(File.java:1704)
      	at java.io.File.createTempFile(File.java:1792)
      	at org.apache.hadoop.util.RunJar.main(RunJar.java:147)
      

      As it is, you need to go into the code, discover that it's ${hadoop.tmp.dir}/hadoop-unjar, but you need to know the value of hadoop.tmp.dir to really find out what the problem is.
