Steve Loughran commented on HADOOP-12911:
-----------------------------------------
MiniKDC does sometimes get used, but it's been weak and not ideal. Limited
support for protocols, a pain to set up, and I could never get it to issue
tickets for >1 person in the same JVM (though that was probably UGI's static
initializers there).
I don't know how much use of MiniKDC there is outside;
[mvnrepo|http://mvnrepository.com/artifact/org.apache.hadoop/hadoop-minikdc/usages]
says: Kafka. HBase, Accumulo ... these are all people we can talk to.
This is the evolution of classic MiniKDC: it will have to move on, what needs
to be done is do it carefully and with users of the module happy.

> 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.
