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.
