Create users in hadoop/HDP 2.5

[#1]

I just created users in /home in edge node for users to work on hadoop. But users not able to run hive/Yarn jobs. My cluster is already kerberized. Is there any way to assign users to submit their jobs in edge node.

Do we need to these users in hadoop/hdfs ?

If cluster has kerberos and ranger is there any different way to do it ?

Please suggest me.

You need to create user directories on HDFS for each user.

$ su - hdfs

Because your cluster is kerberized you need to get a token for the hdfs user. Something like this

$ kinit -k -t /etc/security/keytabs/hdfs.service.keytab hdfs/node1.hadoop.com@HADOOP.COM

Now you can create an HDFS directory for your user.

$ hadoop fs -mkdir /user/berlin
$ hadoop fs -chown berlin /user/berlin

If you're querying Hive, you could use a desktop tool like Aginity Workbench, which supports Kerberos connections.
