Synopsis

Calls the Amazon Elastic MapReduce ListSteps API operation.

Syntax

Get-EMRStepList
-ClusterId <String>
-StepId <String[]>
-StepState <String[]>
-Marker <String>
-Select <String>
-PassThru <SwitchParameter>
-NoAutoIteration <SwitchParameter>

Description

Provides a list of steps for the cluster in reverse order unless you specify stepIds with the request of filter by StepStates. You can specify a maximum of ten stepIDs.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Note: For scripts written against earlier versions of this module this cmdlet can also be invoked with the alias, Get-EMRSteps.

Parameters

-ClusterId <String>
The identifier of the cluster for which to list the steps.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Marker <String>
The pagination token that indicates the next set of results to retrieve.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-Marker $null' for the first call and '-Marker $AWSHistory.LastServiceResponse.Marker' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesNextToken
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of Marker as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the ClusterId parameter. The -PassThru parameter is deprecated, use -Select '^ClusterId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Steps'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ElasticMapReduce.Model.ListStepsResponse). Specifying the name of a property of type Amazon.ElasticMapReduce.Model.ListStepsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-StepId <String[]>
The filter to limit the step list based on the identifier of the steps. You can specify a maximum of ten Step IDs. The character constraint applies to the overall length of the array.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStepIds
-StepState <String[]>
The filter to limit the step list based on certain states.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStepStates

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfileName, StoredCredentials
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases SecretAccessKey, SK
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases ST
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases RegionToCall
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)

Inputs

System.String
You can pipe a String object to this cmdlet for the ClusterId parameter.

Outputs

Amazon.ElasticMapReduce.Model.StepSummary or Amazon.ElasticMapReduce.Model.ListStepsResponse
This cmdlet returns a collection of Amazon.ElasticMapReduce.Model.StepSummary objects. The service call response (type Amazon.ElasticMapReduce.Model.ListStepsResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
