Subject Re: Sharing single hadoop installation for multiple users on cluster
Date Mon, 18 Jan 2016 06:26:39 GMT
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?
