Eric Liang created SPARK-17983:
----------------------------------
Summary: Can't filter over mixed case parquet columns of converted
Hive tables
Key: SPARK-17983
URL: https://issues.apache.org/jira/browse/SPARK-17983
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.1.0
Reporter: Eric Liang
Priority: Critical
We should probably revive https://github.com/apache/spark/pull/14750 in order
to fix this issue and related classes of issues.
The only other alternatives are (1) reconciling on-disk schemas with metastore
schema at planning time, which seems pretty messy, and (2) fixing all the
datasources to support case-insensitive matching, which also has issues.
