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 checks whether a given file is in a format it can handle, and if it is, the classifier creates a schema in the form of a StructType object that matches that data format.

A classifier can be a grok classifier, an XML classifier, or a JSON classifier, asspecified in one of the fields in the Classifier object.
