Hi guys !
Common things done by me :
$chmod -R 777 hadoop_extract
$chmod -R 777 /app
@Joey
I have created dfs dir /user/arun and made arun owner and tried as below
1>
arun@arun-Presario-C500-RU914PA-ACJ:/$ /usr/local/hadoop/bin/hadoop jar
/usr/local/hadoop/hadoop-examples-0.20.203.0.jar wordcount
-Dmapred.job.queue.name=myqueue1 /user/arun/wcin /user/arun/wcout2
Exception in thread "main" java.io.IOException: Permission denied

@Uma
I have Set mapreduce.jobtracker.staging.root.dir propery value in
mapred-site.xml to /user and restartd cluster but that doesn't work.
@Aaron
I have set the config value "dfs.permissions" to "false" in hdfs-site.xml
and restarted.
i get the same error above while running applicn.
Only thing left is : hadoop fs -chmod 777
