get-classifier

Description

Retrieve a classifier by name.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  get-classifier
--name <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--name (string)

Name of the classifier to retrieve.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

Classifier -> (structure)

The requested classifier.

GrokClassifier -> (structure)

A classifier that uses grok .

Name -> (string)

The name of the classifier.

Classification -> (string)

An identifier of the data format that the classifier matches, such as Twitter, JSON, Omniture logs, and so on.

CreationTime -> (timestamp)

The time that this classifier was registered.

LastUpdated -> (timestamp)

The time that this classifier was last updated.

Version -> (long)

The version of this classifier.

GrokPattern -> (string)

The grok pattern applied to a data store by this classifier. For more information, see built-in patterns in Writing Custom Classifiers .

CustomPatterns -> (string)

Optional custom grok patterns defined by this classifier. For more information, see custom patterns in Writing Custom Classifiers .

XMLClassifier -> (structure)

A classifier for XML content.

Name -> (string)

The name of the classifier.

Classification -> (string)

An identifier of the data format that the classifier matches.

CreationTime -> (timestamp)

The time that this classifier was registered.

LastUpdated -> (timestamp)

The time that this classifier was last updated.

Version -> (long)

The version of this classifier.

RowTag -> (string)

The XML tag designating the element that contains each record in an XML document being parsed. This can't identify a self-closing element (closed by / ). An empty row element that contains only attributes can be parsed as long as it ends with a closing tag (for example, row item_a="A" item_b="B"/row is okay, but row item_a="A" item_b="B" / is not).

JsonClassifier -> (structure)

A classifier for JSON content.

Name -> (string)

The name of the classifier.

CreationTime -> (timestamp)

The time that this classifier was registered.

LastUpdated -> (timestamp)

The time that this classifier was last updated.

Version -> (long)

The version of this classifier.

JsonPath -> (string)

A JsonPath string defining the JSON data for the classifier to classify. AWS Glue supports a subset of JsonPath , as described in Writing JsonPath Custom Classifiers .

CsvClassifier -> (structure)

A classifier for comma-separated values (CSV).

Name -> (string)

The name of the classifier.

CreationTime -> (timestamp)

The time that this classifier was registered.

LastUpdated -> (timestamp)

The time that this classifier was last updated.

Version -> (long)

The version of this classifier.

Delimiter -> (string)

A custom symbol to denote what separates each column entry in the row.

QuoteSymbol -> (string)

A custom symbol to denote what combines content into a single column value. It must be different from the column delimiter.

ContainsHeader -> (string)

Indicates whether the CSV file contains a header.

Header -> (list)

A list of strings representing column names.

(string)

DisableValueTrimming -> (boolean)

Specifies not to trim values before identifying the type of column values. The default value is true .

AllowSingleColumn -> (boolean)

Enables the processing of files that contain only one column.
