Description

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

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. 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 | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.
