Liya Fan updated ARROW-13645:
-----------------------------
Description:
As discussed in the ML
(https://lists.apache.org/thread.html/r19aad8a34f63334d3fcd627106f69be13f689740b83930a4eecc17b3%40%3Cdev.arrow.apache.org%3E),
the current implementation use hard-coded field names. This may cause some
problems, for example, when reconstruct a usable schema from a list of
FieldVectors.
So we resolve this problem by allowing NullVectors to have distinct field
names.
This also makes the NullVector with other types of vectors.
