Azure Batch SDK for Java release notes

Changes in 5.0.0

Features

  • [Breaking] Removed support for the ChangeOSVersion API on CloudServiceConfiguration pools.
    • Removed PoolOperations.ChangeOSVersion.
    • Renamed TargetOSVersion to OSVersion and removed CurrentOSVersion on CloudPool.
    • Removed PoolState.Upgrading enum.
  • [Breaking] Removed DataEgressGiB and DataIngressGiB from PoolUsageMetrics. These properties are no longer supported.
  • [Breaking] ResourceFile improvements
    • Added the ability specify an entire Azure Storage container in ResourceFile. There are now three supported modes for ResourceFile:
      • ResourceFile.withUrl creates a ResourceFile pointing to a single HTTP URL.
      • ResourceFile.withStorageContainerUrl creates a ResourceFile pointing to an Azure Blob Storage container.
      • ResourceFile.withAutoStorageContainer creates a ResourceFile pointing to an Azure Blob Storage container in the Batch registered auto-storage account.
        • The BlobPrefix property can be used to filter downloads from a storage container to only those matching the prefix.
    • URLs provided to ResourceFile via the ResourceFile.withUrl method can now be any HTTP URL. Previously, these had to be an Azure Blob Storage URL.
  • [Breaking] Removed OSDisk property from VirtualMachineConfiguration. This property is no longer supported.
  • Pools which set the DynamicVNetAssignmentScope on NetworkConfiguration to be DynamicVNetAssignmentScope.Job can now dynamically assign a Virtual Network to each node the job's tasks run on. The specific Virtual Network to join the nodes to is specified in the new JobNetworkConfiguration property on CloudJob and JobSpecification.
    • Note: This feature is in public preview. It is disabled for all Batch accounts except for those which have contacted us and requested to be in the pilot.
  • The maximum lifetime of a task is now 180 days (previously it was 7).
  • Added support on Windows pools for creating users with a specific login mode (either Batch or Interactive) via WindowsUserConfiguration.LoginMode.
  • The default task retention time for all tasks is now 7 days, previously it was infinite.

REST API version

This version of the Batch .NET client library targets version 2018-12-01.8.0 of the Azure Batch REST API.

Changes in 4.0.1

Fixes

  • Fix missing signing of 4.0.0 Java SDK binary

Changes in 4.0.0

Features

  • Added the functionality to get which version of the Azure Batch Node Agent(https://github.com/Azure/Batch/blob/master/changelogs/nodeagent/CHANGELOG.md) is running on nodes via the NodeAgentInformation property of ComputeNode.
  • Added additional error handling to task add operations to prevent deadlock scenarios.
  • Removed validation status from count operations.
  • Updated adal, azure-client-runtime, and commons-codec dependencies.
  • Update 'List' methods to return the lower layer PagedList object instead of the standard List.

REST API version

This version of the Batch Java client library targets version 2018-08-01.7.1 of the Azure Batch REST API. See this document for detail.

Changes in 3.3.0

Features

  • createTasks rethrow RuntimeException catched by internal threads.
  • createTasks handle RequestSizeTooLarge chunking errors for well behaved tasks.

Changes in 3.2.0

Features

  • Update comments for some classes and properties.
  • Added the leavingPool property to NodeCounts class.

Changes in 3.1.0

Features

  • Added the ability to query pool node counts by state, via the new listPoolNodeCounts method on PoolOperations.
  • Added the ability to upload Azure Batch node agent logs from a particular node, via the uploadComputeNodeBatchServiceLogs method on ComputeNodeOperations.
    • This is intended for use in debugging by Microsoft support when there are problems on a node.

REST API version

This version of the Batch Java client library targets version 2018-03-01.6.1 of the Azure Batch REST API. See this document for detail.

Changes in 3.0.0

Features

  • Added the ability to get a discount on Windows VM pricing if you have on-premises licenses for the OS SKUs you are deploying, via licenseType on VirtualMachineConfiguration.
  • Added support for attaching empty data drives to VirtualMachineConfiguration based pools, via the new dataDisks property on VirtualMachineConfiguration.
  • [Breaking] Custom images must now be deployed using a reference to an ARM Image, instead of pointing to .vhd files in blobs directly.
    • The new virtualMachineImageId property on ImageReference contains the reference to the ARM Image, and OSDisk.imageUris no longer exists.
    • Because of this, imageReference is now a required property of VirtualMachineConfiguration.
  • [Breaking] Multi-instance tasks (created using MultiInstanceSettings) must now specify a coordinationCommandLine, and numberOfInstances is now optional and defaults to 1.
  • Added support for tasks run using Docker containers. To run a task using a Docker container you must specify a containerConfiguration on the VirtualMachineConfiguration for a pool, and then add taskContainerSettings on the Task.

REST API version

This version of the Batch Java client library targets version 2017-09-01.6.0 of the Azure Batch REST API. See this document for detail.
