Setting up Cloudera

This setup is to create a home directory for a kuser1 user in Hadoop HDFS. This is done by using the Cloudera web based administration tools.

More information about the Cloudera setup can be found in Mapping Kerberos Principals to Short Names in the Cloudera documentation.

More information about mapping principals to hdfs users can be found in Configuring the Mapping from Kerberos Principals to Short Names in the Cloudera documentation.

Procedure

Log in to Hue and create a new user called kuser1 and add default as the group.
Using the File Browser, create a home directory for kuser1 user in the /user directory.

In this example, the directory /user/kuser1/ is used as the target directory.
Log in to Cloudera Manager, click hdfs service > Configuration and type Kerberos Realms in the search box to open two properties in the Service-Wide/Security Category.
Within Additional Rules to Map Kerberos Principals to Short Names enter the following rule:
```
RULE:[1:$1@$0](kuser1@CLOUDERA.COM)s/.*/kuser1/
```
Click Save Changes.
