                 Key: SPARK-8838
                 URL: https://issues.apache.org/jira/browse/SPARK-8838
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Liang-Chi Hsieh


Currently all part-files are merged when merging parquet schema. However, in case there are many part-files and we can make sure that all the part-files have the same schema as their summary file. If so, we provide a configuration to disable merging part-files when merging parquet schema.
