Kai Zheng commented on HADOOP-12911:
------------------------------------

Hi [~aw], thanks for your questions!

bq. Why was this committed with a findbugs errors rather than adding the necessary plumbing
in pom.xml to make it go away?
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. I planned to get rid of this   given kerby-1.0.0-rc3
release, by removing the related work around codes totally.
bq. Why wasn't the fix version set in jira?
Yes it's my mistake, I should have been careful about it. Done!
bq. Do we actually need to package all of these extra bits into the distribution tar ball?
I'm not sure I understood this. Did you see any related change affecting this? What we wanted
to change is the involved dependencies, indicated in the pom.xml file.

> 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.
