### Describe the bug, including details regarding any error messages,
version, and platform.
Trying to write a map column to a parquet file using DatasetFileWriter
results in the following error:
`Runtime java.lang.IllegalArgumentException: not all nodes and buffers were
consumed. nodes: [ArrowFieldNode [length=2, nullCount=1], ArrowFieldNode
[length=0, nullCount=0], ArrowFieldNode [length=0, nullCount=0]] buffers:
[ArrowBuf[509], address:140461672595576, capacity:0, ArrowBuf[510],
address:140461672595576, capacity:1, ArrowBuf[511], address:140461672595584,
capacity:8, ArrowBuf[512], address:140461672595592, capacity:0, ArrowBuf[513],
address:140461672595592, capacity:0, ArrowBuf[514], address:140461672595592,
capacity:0]

This happens when the data-to-be-written comes from an ArrowFileReader or
ArrowStreamReader. This problem may affect more file formats than parquet (and
might actually be related to the DatasetFileWriter in general).
