Hello list, I am new on Hadoop, I configura a 3 slaves and 1 master
Hadoop cluster.
The problem is that with normal users I can not execute nothing:
$ hadoop dfs -ls /user/josu.lazkano/gutenberg
Found 7 items
-rw-r--r-- 2 josu.lazkano supergroup 343695 2011-10-11
09:47 /user/josu.lazkano/gutenberg/132.txt.utf8
-rw-r--r-- 2 josu.lazkano supergroup 594933 2011-10-11
09:47 /user/josu.lazkano/gutenberg/1661.txt.utf8
-rw-r--r-- 2 josu.lazkano supergroup 1945886 2011-10-11
09:47 /user/josu.lazkano/gutenberg/19699.txt.utf8
-rw-r--r-- 2 josu.lazkano supergroup 674566 2011-10-11
09:47 /user/josu.lazkano/gutenberg/20417.txt.utf8
-rw-r--r-- 2 josu.lazkano supergroup 1573112 2011-10-11
09:47 /user/josu.lazkano/gutenberg/4300.txt.utf8
-rw-r--r-- 2 josu.lazkano supergroup 1423801 2011-10-11
09:47 /user/josu.lazkano/gutenberg/5000.txt.utf8
-rw-r--r-- 2 josu.lazkano supergroup 393963 2011-10-11
09:47 /user/josu.lazkano/gutenberg/972.txt.utf8
And this happens when I run a jar:
$ hadoop jar /usr/local/hadoop/hadoop-0.20.2-examples.jar
wordcount /user/josu.lazkano/gutenberg/ /user/josu.lazkano/gutenberg_out
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:115)
With "hduser" user there is no problem with same jar execution (this
user start the hdfs).
How could I solve this?
Thanks and best regards.
