* Classifiers are triggered during a crawl task. A classifier checks whether a given file is in a format it can handle.
* If it is, the classifier creates a schema in the form of a StructType object that matches that data
* format.
*
*
* You can use the standard classifiers that AWS Glue provides, or you can write your own classifiers to best categorize
* your data sources and specify the appropriate schemas to use for them. A classifier can be a grok
* classifier, an XML classifier, a JSON classifier, or a custom CSV classifier,
* as specified in one of the fields in the Classifier object.
