Subject [jira] [Commented] (HADOOP-12911) Upgrade Hadoop MiniKDC with Kerby
Date Tue, 31 May 2016 09:27:13 GMT

Steve Loughran commented on HADOOP-12911:
-----------------------------------------

Allen is talking about removing the apache-ds and similar, everything needed for the existing
mini kdc doe.

Bear in mind that anything stripping out dependencies needs to be tested carefully. Don't
just try and rebuild hadoop; install it locally via a "mvn install', then try to rebuild:
Hive, Hbase, Tez  & maybe Spark locally. It does take time, but it finds those transient
problems before Hadoop ships.

> 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.
