>                 URL: https://issues.apache.org/jira/browse/HADOOP-15261
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: minikdc
>    Affects Versions: 3.0.0-alpha3
>            Reporter: PandaMonkey
>            Priority: Major
>         Attachments: 347.patch, hadoop.txt
> Hi, after analyzing hadoop-common-project\hadoop-minikdc\pom.xml, we found that Hadoop
depends on org.apache.kerby:kerb-simplekdc 1.0.1, which transitivity introduced commons-io:2.5.

> At the same time, hadoop directly depends on a older version of commons-io:2.4. By further
look into the source code, these two versions of commons-io have many different features.
The dependency conflict problem brings high risks of "NotClassDefFoundError:" or "NoSuchMethodError"
issues at runtime. Please notice this problem. Maybe upgrading commons-io from 2.4 to 2.5
is a good choice. Hope this report can help you. Thanks!
