    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 consistent with other types of vectors.
