Defined in:


Classifiers are written in Python and triggered during a Crawl Task. You can write your own Classifiers to best categorize your data sources and specify the appropriate schemas to use for them. A Classifier first checks whether a given file is in a format it can handle, and then, if so, creates a schema in the form of a StructType object that matches that data format.
