Highlights since 453-e#

Breaking changes#

  • Legacy file system support for all catalogs has been disabled by default. You must activate the desired file system support with fs.native-azure.enabled,fs.native-gcs.enabled, fs.native-s3.enabled, or fs.hadoop.enabled in each catalog. Use the migration guides for Azure Storage, Google Cloud Storage, and S3 to assist if you have not switched from legacy support.

  • Starburst Helm charts are no longer accessible through the ChartMuseum API. Instead, use the OCI API.

  • Secrets configuration provider setup has been updated to use secrets.toml files. The configuration-provider.config-files property is no longer supported. You must update your configuration to use secrets.toml files.

  • The query.low-memory-killer.delay configuration property has been removed. You must remove this property or the cluster fails to start.

  • The following changes have been made to Ranger access control:

    The ranger-system-access-control value for access-control.name has been deprecated and renamed to legacy-ranger-system-access-control.

    The hive-based-ranger-system-access-control access control option has been renamed to hive-based-ranger.

    The ranger value for the hive.security and delta.security catalog configuration properties has been deprecated and renamed to hive.security=deprecated-ranger and delta.security=deprecated-ranger respectively.

    It is recommended that you migrate to the new configuration in anticipation of the removal of the deprecated properties.
