> Currently, Parquet and ORC data sources don't set their output format class, as we override the output committer in Spark SQL. However, SPARK-8678 ignores user defined output committer class while doing appending to avoid potential issues brought by direct output committers (e.g. {{DirectParquetOutputCommitter}}). This makes both of these data sources fallback to the default output committer retrieved from {{TextOutputFormat}}, which is {{FileOutputCommitter}}. For ORC, it's totally fine since ORC itself just uses {{FileOutputCommitter}}. But for Parquet, {{ParquetOutputCommitter}} also writes the summary files while committing the job.
