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
> KerberosAuthenticatorHandler is not setting KerberosName name rules from
> configuration
