Manoj Chandrashekar updated SPARK-39605:
----------------------------------------
Description:
I have a job that infers schema from mongodb and does operations such as
flattening and unwinding because there are nested fields. After performing
various transformations, finally when the count() is performed, it works
perfectly fine in databricks runtime version 7.3 LTS but fails to perform the
same in 10.4 LTS.
*Below is the image that shows successful run in 7.3 LTS:*

*Below is the image that shows failure in 10.4 LTS:*
