Deprecation Notices for Cloudera Manager

Certain features and functionality are deprecated or removed in Cloudera Manager 7.13.3. You must review these changes along with the information about the features in Cloudera Manager that will be removed or deprecated in a future release.

Removal of legacy CDH 3.x, 4.x, and 5.x cluster management support and API endpoints

Cloudera Manager 7.13.3 removes all legacy code paths, management workflows, and REST API endpoints associated with end-of-support CDH 3.x, 4.x, and 5.x releases. Because CDH 3.x, 4.x, and 5.x reached end-of-support status previously, Cloudera Manager no longer supports managing, monitoring, or configuring these legacy releases.

This change cleans up obsolete code paths and does not impact supported target platforms, such as CDP Private Cloud Base or Cloudera Runtime 7.x.

Affected components and services
Cloudera Manager 7.13.3 removes the following API endpoints and legacy services:
  • HBase Upgrade API:
    • POST /{serviceName}/commands/hbaseUpgrade
  • Low Latency Application Master (LLAMA) Service APIs:

    • POST /{serviceName}/commands/impalaEnableLlamaRm

    • POST /{serviceName}/commands/impalaDisableLlamaRm

    • POST /{serviceName}/commands/impalaEnableLlamaHa

    • POST /{serviceName}/commands/impalaDisableLlamaHa

  • Legacy Services:
    • Sqoop 2 service integration and configuration.
Impact and behavioral changes

  • Management capabilities: Upgrading Cloudera Manager to version 7.13.3 removes all functionality required to manage, monitor, or configure existing CDH 3.x, 4.x, or 5.x clusters.

  • REST API status code changes: Automated scripts or API clients calling removed endpoints now receive an HTTP 404 Not Found response code instead of the previously returned HTTP 400 Bad Request or HTTP 410 Gone status codes.

Action required

Before upgrading Cloudera Manager to version 7.13.3, migrate any remaining CDH 3.x, 4.x, or 5.x workloads and clusters to a supported Cloudera Base on premises release line. Additionally, update any custom automation scripts to remove references to the deprecated LLAMA, Sqoop 2, and HBase upgrade API endpoints.
