update-classifier

Description

Modifies an existing classifier (a GrokClassifier , an XMLClassifier , a JsonClassifier , or a CsvClassifier , depending on which field is present).

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  update-classifier
[--grok-classifier <value>]
[--xml-classifier <value>]
[--json-classifier <value>]
[--csv-classifier <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--grok-classifier (structure)

A GrokClassifier object with updated fields.

Name -> (string)

The name of the GrokClassifier .

Classification -> (string)

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

GrokPattern -> (string)

The grok pattern used by this classifier.

CustomPatterns -> (string)

Optional custom grok patterns used by this classifier.

Shorthand Syntax:

Name=string,Classification=string,GrokPattern=string,CustomPatterns=string

JSON Syntax:

{
  "Name": "string",
  "Classification": "string",
  "GrokPattern": "string",
  "CustomPatterns": "string"
}

--xml-classifier (structure)

An XMLClassifier object with updated fields.

Name -> (string)

The name of the classifier.

Classification -> (string)

An identifier of the data format that the classifier matches.

RowTag -> (string)

The XML tag designating the element that contains each record in an XML document being parsed. This cannot 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).

Shorthand Syntax:

Name=string,Classification=string,RowTag=string

JSON Syntax:

{
  "Name": "string",
  "Classification": "string",
  "RowTag": "string"
}

--json-classifier (structure)

A JsonClassifier object with updated fields.

Name -> (string)

The name of the 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 .

Shorthand Syntax:

Name=string,JsonPath=string

JSON Syntax:

{
  "Name": "string",
  "JsonPath": "string"
}

--csv-classifier (structure)

A CsvClassifier object with updated fields.

Name -> (string)

The name of the 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.

Shorthand Syntax:

Name=string,Delimiter=string,QuoteSymbol=string,ContainsHeader=string,Header=string,string,DisableValueTrimming=boolean,AllowSingleColumn=boolean

JSON Syntax:

{
  "Name": "string",
  "Delimiter": "string",
  "QuoteSymbol": "string",
  "ContainsHeader": "UNKNOWN"|"PRESENT"|"ABSENT",
  "Header": ["string", ...],
  "DisableValueTrimming": true|false,
  "AllowSingleColumn": true|false
}

--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.
