Overview
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.
