Yin Huai created SPARK-2927:
-------------------------------
Summary: Add a conf to always read Binary columns stored in
Parquet as String columns
Key: SPARK-2927
URL: https://issues.apache.org/jira/browse/SPARK-2927
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Yin Huai
Based on Parquet spec (https://github.com/Parquet/parquet-format), "strings are
stored as byte arrays (binary) with a UTF8 annotation". However, if the data
generator does not follow it, we will only read binary values back instead of
string values.
