> Now that Parquet 1.10 is out, we should consider moving to it, if for no other reason
than to address SPARK-23852. 
> There are some non-trivial changes to address. In particular, the [ValuesReader interface|https://github.com/apache/parquet-mr/blob/master/parquet-column/src/main/java/org/apache/parquet/column/values/ValuesReader.java]
has changed from passing data as {{byte[]}} to a {{ByteBufferInputStream}} abstraction that
can hide multiple {{ByteBuffer}}s under the hood.
