MappingExecutionSteps

With the MappingExecutionStats REST API, you can view execution steps for Hadoop jobs. You can also view the scripts for Hadoop jobs with the fetchScripts option.

GET Request

To request information from the MappingExecutionSteps with the associated scripts within the Hadoop scripts, use the following URL:

<RESTOperationsHubService_Host>:<RESTOperationsHubService_Port>/RestOperationsHub/services/v1/MappingService/MappingExecutionSteps(jobId='id',fetchScripts=true)

To request information from the MappingExecutionSteps without the associated scripts within the Hadoop scripts, use the following URL:

<RESTOperationsHubService_Host>:<RESTOperationsHubService_Port>/RestOperationsHub/services/v1/MappingService/MappingExecutionSteps(jobId='id',fetchScripts=false)

The following table describes the required attributes in the MappingExecutionSteps Get URL:

Field	Type	Description
userName	String	Required. User name to connect to the domain. You can pass the input value as a header.
encryptedpassword	String	Required. Password for the user. Encrypt the password with the pmpasswd command line program. You can pass the input value as a header.
securityDomain	String	Optional. The security domain to which the domain user belongs. You can pass the input value as a header.
jobId	String	Required. The argument of the entity that contains the ID for the mappings. You can pass the input value as a query.
fetchScripts	String	Required. Gets all associated scripts within the Hadoop scripts. You can enter true to get the associated run tasks with the scripts. To get the associated run tasks without the scripts, enter false.
