[jira] [Created] (SPARK-23972) Upgrade to Parquet 1.10
Henry Robinson created SPARK-23972:
--------------------------------------
Summary: Upgrade to Parquet 1.10
Key: SPARK-23972
URL: https://issues.apache.org/jira/browse/SPARK-23972
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.4.0
Reporter: Henry Robinson
Now that Parquet 1.10 is out, we should consider moving to it, if for no other reason than to address SPARK-23852.Â
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.
