########## File path: external/avro/src/main/scala/org/apache/spark/sql/avro/AvroOptions.scala ########## @@ -78,7 +80,17 @@ class AvroOptions( parameters .get(AvroOptions.ignoreExtensionKey) .map(_.toBoolean) - .getOrElse(!ignoreFilesWithoutExtension) + .map { ignoreExtensionOption => + if (ignoreExtensionOption != !ignoreFilesWithoutExtensionByDefault) { + warn(s"The Avro option '${AvroOptions.ignoreExtensionKey}'") Review comment: @HyukjinKwon I will check that but general thoughts are: 1. The log warning is printed only if an user sets non-default config values 2. I don't think `AvroOptions` should be created per-each file if it is created in current implementation. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
