The Cloudera Altus release notes lists the new features added in each release and the known issues for the platform.

What's New: September 18, 2017

This release of Cloudera Altus has the following new features:
Machine User Accounts
A machine user account provides programmatic access to the Altus API through the CLI. You can use a machine user account in an application to run Altus processes using CLI commands.
Support for CDH 5.12
You can create Altus clusters with CDH 5.12 or CDH 5.11.
The CDH versions in Altus clusters support different versions of the Spark service. Altus supports the following combinations of CDH and Spark versions:
  • CDH 5.12 with Spark 2.2
  • CDH 5.11 with Spark 2.1 or Spark 1.6
Integration with Cloudera Navigator
You can use Cloudera Navigator to generate analytics and data lineage from Altus clusters and workloads. In Altus, select the option to send cluster and workload metadata to an S3 bucket accessible to Cloudera Navigator. In Cloudera Navigator, configure the S3 bucket as a resource for metadata extraction.

To enable integration with Cloudera Navigator using the CLI, download the latest version of the Altus client.

What's New: June 22, 2017

This release of Cloudera Altus has the following new features:
Workload Analytics
Workload Analytics is a tool that can be used to identify and troubleshoot issues with a job. When you access Workload Analytics through the Altus console, you can view the health checks and baselines for completed jobs that compare the current performance to past runs of the same job as well as the performance of tasks within the same job.

To use Workload Analytics, you must select the Enable Workload Analytics option when you create an Altus environment.

Support for Spot Instances
If you want to increase the number of nodes in your cluster to improve job performance, you can use Spot instances for compute worker nodes in your cluster. Compute worker nodes are nodes that run computational processes. A Spot instance is an EC2 instance with a low hourly price that you can bid on. Spot instances become available when your bid price is higher than the current market price and they terminate when your bid price is below market price. Using Spot instances allows you to run a large number of job processes on cheaper instances and is a cost-effective way to meet a service level agreement.

Cloudera Altusには以下の既知の問題があります。
パスワードで保護されたSSHキーの非サポート
Cloudera Altusは、パスワードで保護されたSSHキーをサポートしません。SSHキーを作成する際には、パスワード(あるいはパスフレーズ)をキーに設定しないようにしてください。-Nパラメータに空文字を指定すれば、パスワードのプロンプトをスキップできます。例: ssh-keygen -N ''
再利用されたEnvironment名のWorkload Analyticsにおける非サポート
Workload Analyticsは、削除されたEnvironmentと同じ名前を持つEnvironmentを使うクラスターで実行されたジョブに関するレポートを表示しません。
回避方法: Environmentを作成する差異には、それまでに使われたことのない名前を選択してください。
