             Summary: New option - ignoreExtension
                 Key: SPARK-24836
                 URL: https://issues.apache.org/jira/browse/SPARK-24836
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.3.1
            Reporter: Maxim Gekk


Need to add new option for Avro datasource - *ignoreExtension*. It should control ignoring of the .avro extensions. If it is set to *true* (by default), files with and without .avro extensions should be loaded. Example of usage:
{code:scala}
spark
  .read
  .option("ignoreExtension", false)
  .avro("path to avro files")
{code}

The option duplicates Hadoop's config avro.mapred.ignore.inputs.without.extension which is taken into account by Avro datasource now and can be set like:
{code:scala}
spark
  .sqlContext
  .sparkContext
  .hadoopConfiguration
  .set("avro.mapred.ignore.inputs.without.extension", "true")
{code}

The ignoreExtension option must override avro.mapred.ignore.inputs.without.extension.
