             Summary: Fail to load user's class if user move 
hudi-spark-bundle_2.11-0.7.0.jar into spark classpath
                 Key: HUDI-1750
                 URL: https://issues.apache.org/jira/browse/HUDI-1750
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: lrz
             Fix For: 0.9.0
         Attachments: image-2021-04-01-10-55-43-760.png

Hudi use Class.forName(clazzName) to load user's class, which classloader is 
same as call,see here:

if user move hudi-spark-bundle jar into spark classPath, and use --jar to add 
customer jars, then the caller classLoader will be AppClassLoader, and the 
customer jars will be load by spark's MutableURLClassLoader, then lead to 
ClassNotFoundException
