TaskAddParameter Class

public class TaskAddParameter

An Azure Batch Task to add. Batch will retry Tasks when a recovery operation is triggered on a Node. Examples of recovery operations include (but are not limited to) when an unhealthy Node is rebooted or a Compute Node disappeared due to host failure. Retries due to recovery operations are independent of and are not counted against the maxTaskRetryCount. Even if the maxTaskRetryCount is 0, an internal retry due to a recovery operation may occur. Because of this, all Tasks should be idempotent. This means Tasks need to tolerate being interrupted and restarted without causing any corruption or duplicate data. The best practice for long running Tasks is to use some form of checkpointing.

Constructor Details

TaskAddParameter

public TaskAddParameter()

Method Details

affinityInfo

public AffinityInformation affinityInfo()

Get the affinityInfo value.

Returns:

the affinityInfo value

applicationPackageReferences

public List applicationPackageReferences()

Get application packages are downloaded and deployed to a shared directory, not the Task working directory. Therefore, if a referenced package is already on the Node, and is up to date, then it is not re-downloaded; the existing copy on the Compute Node is used. If a referenced Package cannot be installed, for example because the package has been deleted or because download failed, the Task fails.

Returns:

the applicationPackageReferences value

authenticationTokenSettings

public AuthenticationTokenSettings authenticationTokenSettings()

Get if this property is set, the Batch service provides the Task with an authentication token which can be used to authenticate Batch service operations without requiring an Account access key. The token is provided via the AZ_BATCH_AUTHENTICATION_TOKEN environment variable. The operations that the Task can carry out using the token depend on the settings. For example, a Task can request Job permissions in order to add other Tasks to the Job, or check the status of the Job or of other Tasks under the Job.

Returns:

the authenticationTokenSettings value

commandLine

public String commandLine()

Get for multi-instance Tasks, the command line is executed as the primary Task, after the primary Task and all subtasks have finished executing the coordination command line. The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. If the command line refers to file paths, it should use a relative path (relative to the Task working directory), or use the Batch provided environment variable (https://docs.microsoft.com/en-us/azure/batch/batch-compute-node-environment-variables).

Returns:

the commandLine value

constraints

public TaskConstraints constraints()

Get if you do not specify constraints, the maxTaskRetryCount is the maxTaskRetryCount specified for the Job, the maxWallClockTime is infinite, and the retentionTime is 7 days.

Returns:

the constraints value

containerSettings

public TaskContainerSettings containerSettings()

Get if the Pool that will run this Task has containerConfiguration set, this must be set as well. If the Pool that will run this Task doesn't have containerConfiguration set, this must not be set. When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all Task environment variables are mapped into the container, and the Task command line is executed in the container. Files produced in the container outside of AZ_BATCH_NODE_ROOT_DIR might not be reflected to the host disk, meaning that Batch file APIs will not be able to access those files.

Returns:

the containerSettings value

dependsOn

public TaskDependencies dependsOn()

Get this Task will not be scheduled until all Tasks that it depends on have completed successfully. If any of those Tasks fail and exhaust their retry counts, this Task will never be scheduled. If the Job does not have usesTaskDependencies set to true, and this element is present, the request fails with error code TaskDependenciesNotSpecifiedOnJob.

Returns:

the dependsOn value

displayName

public String displayName()

Get the display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.

Returns:

the displayName value

environmentSettings

public List environmentSettings()

Get the environmentSettings value.

Returns:

the environmentSettings value

exitConditions

public ExitConditions exitConditions()

Get how the Batch service should respond when the Task completes.

Returns:

the exitConditions value

id

public String id()

Get the ID can contain any combination of alphanumeric characters including hyphens and underscores, and cannot contain more than 64 characters. The ID is case-preserving and case-insensitive (that is, you may not have two IDs within a Job that differ only by case).

Returns:

the id value

multiInstanceSettings

public MultiInstanceSettings multiInstanceSettings()

Get the multiInstanceSettings value.

Returns:

the multiInstanceSettings value

outputFiles

public List outputFiles()

Get for multi-instance Tasks, the files will only be uploaded from the Compute Node on which the primary Task is executed.

Returns:

the outputFiles value

requiredSlots

public Integer requiredSlots()

Get the default is 1. A Task can only be scheduled to run on a compute node if the node has enough free scheduling slots available. For multi-instance Tasks, this must be 1.

Returns:

the requiredSlots value

resourceFiles

public List resourceFiles()

Get for multi-instance Tasks, the resource files will only be downloaded to the Compute Node on which the primary Task is executed. There is a maximum size for the list of resource files. When the max size is exceeded, the request will fail and the response error code will be RequestEntityTooLarge. If this occurs, the collection of ResourceFiles must be reduced in size. This can be achieved using .zip files, Application Packages, or Docker Containers.

Returns:

the resourceFiles value

userIdentity

public UserIdentity userIdentity()

Get if omitted, the Task runs as a non-administrative user unique to the Task.

Returns:

the userIdentity value
