title: AWS Glue Crawler - Reading a gzip file of csv
body: <p>Can you please help me with reading a tar.gz file using Glue Data crawler please? I have a tar.gz file which contains couple of files in different schema in my S3, and when I try to run a crawler, I don't see the schema in the data catalogue. Should we use any custom classifiers?  The AWS Glue FAQ specifies that gzip is supported using classifiers, but is not listed in the classifiers list provided in the Glue Classifier sections.</p>
