-Hmm. It seems that there is more patches for this in addition to that. Let me
dig more.-
SPARK-27034 is correct. You need the following especially to backport what you
want.

> struct<a:struct<a1:int,a2:string,a3:timestamp,a4:string,a5:int>,b:struct<b1:int,b2:string>>
> {code}
> The difference is about the ORC reader, orc-mapreduce-1.5.5-nohive and
> orc-mapreduce-1.5.9
> I simply tried upgrade orc-mapreduce-1.5.5-nohive to
> orc-mapreduce-1.5.9-nohive and it doesn't fix the problem.
> Is there any way to fix this in branch-2.4?
