Vinayakumar B commented on HADOOP-12911:
----------------------------------------

I am sorry for coming in late for this,
I have one quick comment/suggestion, can be fixed in follow up jira.
{code}<groupId>org.apache.kerby</groupId>
<artifactId>kerb-simplekdc</artifactId>
<version>1.0.0-RC2</version>{code}
{{hadoop-project/pom.xml}} contains the dependencies of all libraries used in 
all modules of hadoop,  under {{dependencyManagement}}. Only here {{version}} 
will be mentioned. All other Hadoop Modules will inherit {{hadoop-project}}, so 
all submodules will use the same version. In submodule, {{version}} need not be 
mentioned in pom.xml. This will make version management easier.

> As discussed in the mailing list, we’d like to introduce Apache Kerby into 
> Hadoop. Initially it’s good to start with upgrading Hadoop MiniKDC with Kerby 
> offerings. Apache Kerby (https://github.com/apache/directory-kerby), as an 
> Apache Directory sub project, is a Java Kerberos binding. It provides a 
> SimpleKDC server that borrowed ideas from MiniKDC and implemented all the 
> facilities existing in MiniKDC. Currently MiniKDC depends on the old Kerberos 
> implementation in Directory Server project, but the implementation is stopped 
> being maintained. Directory community has a plan to replace the 
> implementation using Kerby. MiniKDC can use Kerby SimpleKDC directly to avoid 
> depending on the full of Directory project. Kerby also provides nice identity 
> backends such as the lightweight memory based one and the very simple json 
> one for easy development and test environments.
