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!
