[jira] [Created] (SPARK-23509) Upgrade commons-net from 2.2 to 3.1

PandaMonkey created SPARK-23509:
-----------------------------------

             Summary: Upgrade commons-net from 2.2 to 3.1
                 Key: SPARK-23509
                 URL: https://issues.apache.org/jira/browse/SPARK-23509
             Project: Spark
          Issue Type: Dependency upgrade
          Components: Spark Core
    Affects Versions: 2.4.0
            Reporter: PandaMonkey
             Fix For: 2.4.0
         Attachments: spark.txt

Hi, after analyzing spark-master\core\pom.xml, we found that Spark-core depends on org.apache.hadoop:hadoop-client:2.6.5, which transitivity introduced commons-net:3.1. At the same time, Spark-core directly depends on a older version of commons-net:2.2. By further look into the source code, these two versions of commons-net 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-net from 2.2 to 3.1 is a good choice. Please notice this problem. Hope this report can help you. Thanks!

 

Regards,

Panda
