Description

It is not possible in the version 1.3.0 of Flume to parse UK or US date from a French computer using the interceptor RegexExtractorInterceptorMillisSerializer.

Indeed, the DateTimeFormatter created in the interceptor is currently using the default Locale which is FR on my computer. When I try to parse some files I got from US, I got the following exception:

The solution I propose is to add a new property called "language" to the interceptor which will allow us to override the default Locale.
