             Summary: Add file filtering interface for FileFormat
                 Key: SPARK-16317
                 URL: https://issues.apache.org/jira/browse/SPARK-16317
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Cheng Lian


{{FileFormat}} data sources like Parquet and Avro (provided by spark-avro) have 
customized file filtering logics. For example, Parquet needs to filter out 
summary files, while Avro provides a Hadoop configuration option to filter out 
all files whose names don't end with ".avro".

It would be nice to have a general file filtering interface in {{FileFormat}} 
to handle similar requirements.
