What's New

Pipelines and most pipeline stages include advanced options with default values that should work in most cases. By default, new and upgraded pipelines hide the advanced options. Advanced options can include individual properties or complete tabs.

• HTTP Client processor - The Missing Values Behavior property determines the action that occurs when a request generates no response.
• Amazon S3 stages - "IAM roles" are now known as "instance profiles" in all Amazon S3 stages. This does not affect existing pipelines.

• Error records - Error records include Control Hub job information in jobName and jobId record header attributes.
• Default password for Google Cloud Platform marketplace installation - The default password for Data Collector installed through the Google Cloud Platform marketplace is now the VM Instance Id. Previously, the default password was admin.

• Pipeline run summary - Information about the most recent pipeline run remains available on the Summary tab of the pipeline after the pipeline stops. The summary includes run details such as the start time and duration.
• Pipeline start and stop events - The event records generated when a pipeline starts and stops include fields for the related Control Hub job ID and job name.
• Stage library panel display and stage installation:
  • The stage library panel displays all Data Collector stages, instead of only the installed stages. Stages that are not installed appear disabled, or greyed out.
  • When you click on a disabled stage, you can install the stage library that includes the stage.

• Data Collector production batch size - The default value for the production.maxBatchSize property in the Data Collector configuration file has increased to 50,000 records. This change does not affect existing pipelines.

• Databricks ML Evaluator processor - This processor is deprecated and will be removed in a future release. Do not use the processor in new pipelines.

• SFTP/FTP/FTPS executor - Use the executor to move or remove a file from an SFTP, FTP, or FTPS server upon receiving an event.

  • You can now configure the Maximum Number of Worker Threads property to limit the number of threads that the destination uses.
  • You can now configure an Admin Operation Timeout property to determine how many milliseconds to allow for admin-type operations, such as opening a table or getting a table schema.

• Data Collector now includes a SPARK_KAFKA_VERSION environment variable that is set to 0.10 by default in the Data Collector environment configuration file - sdc.env.sh or sdcd.env.sh. Do not change this environment variable value. This variable is used only when you run cluster streaming mode pipelines on a Cloudera CDH cluster.

• Directory origin enhancements - The origin includes the following enhancements:
  • The Max Files in Directory property has been renamed to Max Files Soft Limit. As the name indicates, the property is now a soft limit rather than a hard limit.
