   ### 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]
           at org.apache.arrow.vector.VectorLoader.load(VectorLoader.java:89)
           at org.apache.arrow.vector.ipc.ArrowReader.loadRecordBatch(ArrowReader.java:220)
           at org.apache.arrow.vector.ipc.ArrowStreamReader.loadNextBatch(ArrowStreamReader.java:161)
           at org.apache.arrow.c.ArrayStreamExporter$ExportedArrayStreamPrivateData.getNext(ArrayStreamExporter.java:72)`
   
   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).
