setEndpoint
public void setEndpoint(String endpoint)
Description copied from interface:DataPipeline
Overrides the default endpoint for this client ("datapipeline.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.Callers can pass in just the endpoint (ex: "datapipeline.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "datapipeline.us-east-1.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's
ClientConfiguration
will be used, which by default is HTTPS.For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
- Specified by:
setEndpoint
in interfaceDataPipeline
- Parameters:
endpoint
- The endpoint (ex: "datapipeline.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "datapipeline.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
-
setRegion
public void setRegion(Region region)
Description copied from interface:DataPipeline
An alternative toDataPipeline.setEndpoint(String)
, sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the
ClientConfiguration
supplied at construction.This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
- Specified by:
setRegion
in interfaceDataPipeline
- Parameters:
region
- The region this client will communicate with. SeeRegion.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.- See Also:
Region.getRegion(com.amazonaws.regions.Regions)
,Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)
,Region.isServiceSupported(String)

pollForTask
public PollForTaskResult pollForTask(PollForTaskRequest request)
Description copied from interface:DataPipeline
Task runners call
PollForTask
to receive a task to perform from AWS Data Pipeline. The task runner specifies which tasks it can perform by setting a value for theworkerGroup
parameter. The task returned can come from any of the pipelines that match theworkerGroup
value passed in by the task runner and that was launched using the IAM user credentials specified by the task runner.If tasks are ready in the work queue,
PollForTask
returns a response immediately. If no tasks are available in the queue,PollForTask
uses long-polling and holds on to a poll connection for up to a 90 seconds, during which time the first newly scheduled task is handed to the task runner. To accomodate this, set the socket timeout in your task runner to 90 seconds. The task runner should not callPollForTask
again on the sameworkerGroup
until it receives a response, and this can take up to 90 seconds.- Specified by:
pollForTask
in interfaceDataPipeline
- Parameters:
request
- Contains the parameters for PollForTask.- Returns:
- Result of the PollForTask operation returned by the service.
-
putPipelineDefinition
public PutPipelineDefinitionResult putPipelineDefinition(PutPipelineDefinitionRequest request)
Description copied from interface:DataPipeline
Adds tasks, schedules, and preconditions to the specified pipeline. You can use
PutPipelineDefinition
to populate a new pipeline.PutPipelineDefinition
also validates the configuration as it adds it to the pipeline. Changes to the pipeline are saved unless one of the following three validation errors exists in the pipeline.- An object is missing a name or identifier field.
- A string or reference field is empty.
- The number of objects in the pipeline exceeds the maximum allowed objects.
- The pipeline is in a FINISHED state.
Pipeline object definitions are passed to the
PutPipelineDefinition
action and returned by the GetPipelineDefinition action.- Specified by:
putPipelineDefinition
in interfaceDataPipeline
- Parameters:
request
- Contains the parameters for PutPipelineDefinition.- Returns:
- Result of the PutPipelineDefinition operation returned by the service.

-
reportTaskProgress
public ReportTaskProgressResult reportTaskProgress(ReportTaskProgressRequest request)
Description copied from interface:DataPipeline
Task runners call
ReportTaskProgress
when assigned a task to acknowledge that it has the task. If the web service does not receive this acknowledgement within 2 minutes, it assigns the task in a subsequent PollForTask call. After this initial acknowledgement, the task runner only needs to report progress every 15 minutes to maintain its ownership of the task. You can change this reporting time from 15 minutes by specifying areportProgressTimeout
field in your pipeline.If a task runner does not report its status after 5 minutes, AWS Data Pipeline assumes that the task runner is unable to process the task and reassigns the task in a subsequent response to PollForTask. Task runners should call
ReportTaskProgress
every 60 seconds.- Specified by:
reportTaskProgress
in interfaceDataPipeline
- Parameters:
request
- Contains the parameters for ReportTaskProgress.- Returns:
- Result of the ReportTaskProgress operation returned by the service.
-
reportTaskRunnerHeartbeat
public ReportTaskRunnerHeartbeatResult reportTaskRunnerHeartbeat(ReportTaskRunnerHeartbeatRequest request)
Description copied from interface:DataPipeline
Task runners call
ReportTaskRunnerHeartbeat
every 15 minutes to indicate that they are operational. If the AWS Data Pipeline Task Runner is launched on a resource managed by AWS Data Pipeline, the web service can use this call to detect when the task runner application has failed and restart a new instance.- Specified by:
reportTaskRunnerHeartbeat
in interfaceDataPipeline
- Parameters:
request
- Contains the parameters for ReportTaskRunnerHeartbeat.- Returns:
- Result of the ReportTaskRunnerHeartbeat operation returned by the service.
-
setStatus
public SetStatusResult setStatus(SetStatusRequest request)
Description copied from interface:DataPipeline
Requests that the status of the specified physical or logical pipeline objects be updated in the specified pipeline. This update might not occur immediately, but is eventually consistent. The status that can be set depends on the type of object (for example, DataNode or Activity). You cannot perform this operation on
FINISHED
pipelines and attempting to do so returnsInvalidRequestException
.- Specified by:
setStatus
in interfaceDataPipeline
- Parameters:
request
- Contains the parameters for SetStatus.- Returns:
- Result of the SetStatus operation returned by the service.
-
setTaskStatus
public SetTaskStatusResult setTaskStatus(SetTaskStatusRequest request)
Description copied from interface:DataPipeline
Task runners call
SetTaskStatus
to notify AWS Data Pipeline that a task is completed and provide information about the final status. A task runner makes this call regardless of whether the task was sucessful. A task runner does not need to callSetTaskStatus
for tasks that are canceled by the web service during a call to ReportTaskProgress.- Specified by:
setTaskStatus
in interfaceDataPipeline
- Parameters:
request
- Contains the parameters for SetTaskStatus.- Returns:
- Result of the SetTaskStatus operation returned by the service.
-
validatePipelineDefinition
public ValidatePipelineDefinitionResult validatePipelineDefinition(ValidatePipelineDefinitionRequest request)
Description copied from interface:DataPipeline

- Specified by:
validatePipelineDefinition
in interfaceDataPipeline
- Parameters:
request
- Contains the parameters for ValidatePipelineDefinition.- Returns:
- Result of the ValidatePipelineDefinition operation returned by the service.
-
shutdown
public void shutdown()
Description copied from interface:DataPipeline
Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.- Specified by:
shutdown
in interfaceDataPipeline
-
getCachedResponseMetadata
public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
Description copied from interface:DataPipeline
Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.
- Specified by:
getCachedResponseMetadata
in interfaceDataPipeline
- Parameters:
request
- The originally executed request.- Returns:
- The response metadata for the specified request, or null if none is available.
