Zhu Zhu commented on FLINK-14037:
---------------------------------
[~liupengcheng] I mocked this case by creating 2 jars. Jar1 contains class
x.y.z.A. Jar2 contains class x.y.z.A and its subclass z.y.z.B.
A Flink test case is added with classloader1 on Jar1 and its child classloader2
on Jar2. classloader2 can be a parent first classloader or a child first class
loader with "x.y.z." as alwaysParentFirstPatterns.
It turned out to be that the class A is always loaded from Jar1, no matter what
kind of class loader is used.
Therefore the
[result|https://issues.apache.org/jira/browse/FLINK-14037?focusedCommentId=16930345&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16930345]
with your fix does not seem to be expected, unless
"org.apache.hadoop.mapreduce.lib.input.FileInputFormat" does not exist in the
system classloader.
