             Summary: Add an option to return an empty DataFrame from an RDD generated by a Hadoop file
                 Key: SPARK-23395
                 URL: https://issues.apache.org/jira/browse/SPARK-23395
             Project: Spark
          Issue Type: Improvement
          Components: Input/Output
    Affects Versions: 2.2.1, 2.2.0
            Reporter: Jens Rabe


When using file-based data from custom formats, Spark's ability to use Hadoop's FileInputFormats is very handy. However, when the path they are pointed at contains no usable data, they throw an IOException saying "No input paths specified in job".

It would be a nice feature if the DataFrame API somehow could capture this and return an empty DataFrame instead of failing the job.
