[jira] [Created] (SPARK-17983) Can't filter over mixed case parquet columns of converted Hive tables

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.
