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 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.
