    Description

      I can't read Parquet files from ABFS. It has 2 different implementations to read seekable streams, and it'll use the one that uses ByteBuffer reads if it can. It currently decides to use the ByteBuffer read implementation because the FSDataInputStream it gets back wraps another FSDataInputStream, which implements ByteBufferReadable.

      That's not the most robust way to check that ByteBufferReads are supported by the ultimately underlying InputStream, but it's unnecessary and probably a mistake to double-wrap the InputStream, so let's not.
