Github user jerryshao commented on the issue: https://github.com/apache/spark/pull/12203 Can you make sure the problem you met is exactly the same as what this PR solved? Since the exception stack you pasted in the StackOverFlow is different from What I pasted here before. From you exception stack, what I could guess is that same jar (same path with same file name) added twice, this is a little different from this PR's mentioned problem.
