    Description

      The pyarrow.parquet.read_pandas implementation doesn't conform to its docs in at least these ways:

      1. The docs state that a filesystem option can be provided, as it should be. Without this option I cannot read from S3, etc. The implementation, however, doesn't have this option! As such I currently cannot use it to read from S3!
      2. The docs (not in the type definition!) state that the default value for use_legacy_dataset is False, whereas the implementation has a value of True. Actually, however, if a value of True is used, then I can't read a partitioned dataset at all, so in this case maybe its the doc that needs to change to True.

      It looks to have been implemented and reviewed pretty carelessly.
