zhao bo commented on SPARK-28770:
---------------------------------
Thanks Lim, yeah, we also found that most test jobs will pass towards these
tests. For us, It's hard to say this issue is trully exist on X86, but on ARM,
we failed every time.
Hope team can see what happened. What we do on ARM, is just revert the commit
[https://github.com/apache/spark/pull/23767], then all pass.
