COD supports rolling operating system upgrades of a COD cluster

COD using HDFS and Object Store without Ephemeral Storage, now supports upgrading the operating system version of the database using the rolling restart mode. This ensures continuous service availability during an upgrade operation.

In CDP CLI, you need to use the --os-upgrade-only option along with the --rolling-upgrade option in the upgrade-database command.

Following is a sample command.

cdp opdb upgrade-database --environment <environment-name> --database <database-name> [--runtime <runtime-version> | --image <imageId>] --os-upgrade-only --rolling-upgrade

For more information, see Performing a Cloudera operating system upgrade.

COD introduces a new CDP CLI option --storage-type in the create-database command

In CDP CLI, a new option --storage-type in the create-database command is introduced that replaces the [--use-hdfs | --no-use-hdfs] and [--disable-ephemeral-storage | --no-disable-ephemeral-storage] options.

The --storage-type option supports these values, CLOUD_WITH_EPHEMERAL, CLOUD, and HDFS.

Following is a sample command.

cdp opdb create-database --environment <environment-name> --database <database-name> --storage-type CLOUD
