      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 either a grok classifier or an XML classifier, specified in one or the other field of the Classifier object.

          The time this classifier was registered.

        • LastUpdated (datetime) --

          The time this classifier was last updated.

          The version of this classifier.

        • GrokPattern (string) --
