Upgrade your COD cluster without downtime
Released on August 10, 2023
You can now upgrade the Cloudera Runtime version and the operating system version of the database that uses HDFS and Object Store without Ephemeral Storage, in a rolling restart mode.
Previously, while performing a Cloudera Runtime upgrade, users experienced HBase or Phoenix service downtime provided by COD. You can now avoid a service outage of a COD cluster while performing a Cloudera Runtime upgrade.
This feature ensures continuous service availability.
To upgrade the Cloudera Runtime version, use the --rolling-upgrade | --no-rolling-upgrade option on CDP CLI with the upgrade-database command.
Create your COD cluster on a cloud environment with ephemeral storage
COD introduces a new UI option, Cloud With Ephemeral Storage while creating a new operational database. You can set the storage type for the database using this UI option. This option is equivalent to using the --storage-type CLOUD_WITH_EPHEMERAL option on CDP CLI while creating an operational database.
Previously, users were limited to using the CDP CLI to select the storage type; now they don’t need to use the CLI when creating a new COD cluster with cloud storage and using ephemeral caching.
