Subject: [jira] [Updated] (HADOOP-7887) KerberosAuthenticatorHandler is not
 setting KerberosName name rules from configuration

Alejandro Abdelnur updated HADOOP-7887:
---------------------------------------

    Attachment: HADOOP-7887.patch

The attached patch configures the name rules as part of the configuration of the KerberosAuthenticatorHandler.

Verified Kerberos testcases pass and added a new test to test this setting happens.

The UGI on initialization (first call to *isSecurityEnabled()* ) reads the name rules for Hadoop configuration files (-site.xml). It is not possible to se a different name rule directly. 

So, the trick is, if using hadoop-auth outside of Hadoop (ie by Oozie) set the name rules in the hadoop-auth configuration properties and call UGI.isSecurityEnabled() before the KerberosAuthenticationHandler is initialized. If using it from Hadoop no need to set it in the hadoop-auth configuration, it will use the one set by UGI
