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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

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. 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.

CustomDatatypeConfigured -> (boolean)

Enables the custom datatype to be configured.

CustomDatatypes -> (list)

A list of custom datatypes including "BINARY", "BOOLEAN", "DATE", "DECIMAL", "DOUBLE", "FLOAT", "INT", "LONG", "SHORT", "STRING", "TIMESTAMP".

(string)

Serde -> (string)

Sets the SerDe for processing CSV in the classifier, which will be applied in the Data Catalog. Valid values are OpenCSVSerDe , LazySimpleSerDe , and None . You can specify the None value when you want the crawler to do the detection.
