Allen Wittenauer commented on HADOOP-12911:
-------------------------------------------

bq. Sorry I'm not aware of that it's a must-to-do instead of better-to-do to make findbug
issues go away, as we do for check style issues.

Well, now you know. 

bq.  Did you see any related change affecting this? What we wanted to change is the involved
dependencies, indicated in the pom.xml file.

If we're changing this, it seems like an ideal time to strip dependencies out of the dist
since this is clearly going to change what gets bundled.

> 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.
