>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.4.0

> 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.
