      Description

      Trying to write a zero-RecordBatch file to parquet:

      import pyarrow
      import pyarrow.parquet
      table = pyarrow.Table.from_batches([], pyarrow.schema([('A', pyarrow.dictionary(pyarrow.int32(), pyarrow.string()))]))
      pyarrow.parquet.write_table(table, 'x.parquet')
      

      ... I receive an error and Python exits with exit code 139:
