[jira] [Created] (HADOOP-15261) Upgrade commons-io from 2.4 to 2.5

PandaMonkey created HADOOP-15261:
------------------------------------

             Summary: Upgrade commons-io from 2.4 to 2.5
                 Key: HADOOP-15261
                 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
         Attachments: 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, Spark-core 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!
