Description

We moved to the Arrow IO interfaces as part of https://issues.apache.org/jira/browse/PARQUET-1422

However, the BufferedInputStream implementations between Parquet and Arrow are different.

Parquet's BufferedInputStream used to takes a RandomAccessSource. Arrow's implementation takes an InputStream. As a result, the ::arrow::io::BufferedInputStream::Peek(which invokes Read()) implementation causes the raw source (input to BufferedInputStream) to change its offset on Peek(). This did not happen in the Parquet's BufferedInputStream implementation.
