[jira] [Created] (ARROW-13645) [Java] Allow NullVectors to have distinct field names

Liya Fan created ARROW-13645:
--------------------------------

             Summary: [Java] Allow NullVectors to have distinct field names
                 Key: ARROW-13645
                 URL: https://issues.apache.org/jira/browse/ARROW-13645
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java
            Reporter: Liya Fan
            Assignee: Liya Fan
             Fix For: 6.0.0


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.
