Micah Kornfield updated ARROW-6738:
-----------------------------------
Description:
There are some problems with the current union comparison logic. For example:
1. For type check, we should not require fields to be equal. It is possible
that two vectors' value ranges are equal but their fields are different.

There are some problems with the current union comparison logic. For example:
1. For type check, we should not require fields to be equal. It is possible
that two vectors' value ranges are equal but their fields are different.
2. We should not compare the number of sub vectors, as it is possible that two
union vectors have different numbers of sub vectors, but have equal values in
the range.
