You should also set the dfs permissions
Simply run
hadoop fs -chmod 777 /
or set the 'dfs.permissions' to 'false'.

If you started Hadoop daemons with hduser, it will not be shown for
the user foo(or any other user) as hadoop daemons are just java
processes. But still you can run your jobs with any other user. Ensure
that the user foo has access to hadoop directories. And you also don't
have to create a directory in hdfs for the user. I hope this resolves
your problem.
hduser $ start-all.sh
hduser $ su - other
other $ /home/hduser/hadoop203/bin/hadoop jar
/home/hduser/hadoop203/hadoop-examples*.jar pi 1 1

Hi Mohit,
Thanks for your reply. Let me elaborate my problem in detail.
I have installed hadoop with user called 'hduser' and the HADOOP_HOME
points to one folder in hduser's home directory . Now I have added
another user foo in the cluster. I modified the access permissions
for following directories to 777:
1. Hadoop installation directory ( pointed by HADOOP_HOME)
2. dfs.datanode.data.dir
3. dfs.namenode.name.dir
4. hadoop.tmp.dir
I have also created directory /user/foo inside hdfs
After starting hdfs and yarn daemons, I am not able to view these
processes in foo user and so not able to submit jobs.
Can you point out what I am missing here?
Thanks

Hadoop uses the linux system users. I think, You don't have to
make any changes, Just create a new user in your system and give
it access to hadoop ie. provide permissions to hadoop
installation and data directories.

Hi Hadoop user,
I have hadoop-2.6 installed on my cluster with 11 nodes. I have
installed it under one specific user. Now I want to allow other
users on the cluster to share the same hadoop installation. What
changes I need to do in order to allow access to other users?
Thanks
Ravikant
