Wes McKinney commented on PARQUET-1636:
---------------------------------------

I just created https://issues.apache.org/jira/browse/ARROW-6180, that might be 
a solution if your problem results from multithreading

> [C++] Incompatibility due to moving from Parquet to Arrow IO interfaces
> -----------------------------------------------------------------------

>                 Key: PARQUET-1636
>                 URL: https://issues.apache.org/jira/browse/PARQUET-1636
>             Project: Parquet
>          Issue Type: Improvement
>          Components: parquet-cpp
>            Reporter: Deepak Majeti

> 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, theĀ 
> {{::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.
