Upgrading from Medium Duty to Enterprise Data Lake
Refer to this content for an overview of the Data Lake resizing from Medium Duty to Enterprise Data Lake. The resizing of Medium Duty Data Lakes to Enterprise Data Lake should be performed on Cloudera Runtime 7.2.17 and is a prerequisite for upgrading to Cloudera Runtime 7.2.18 or 7.3.1.
Starting with Cloudera Runtime 7.2.18, Medium Duty Data Lake is discontinued and is replaced by Enterprise Data Lake. While earlier Cloudera Runtime versions support Medium Duty Data Lake (7.2.17 supports Enterprise, Medium Duty, Light Duty, and older versions support Medium Duty and Light Duty), 7.2.18 and later versions only support Enterprise and Light Duty Data Lakes.
Enterprise Data Lake enables Horizontal Scaling and Zero-Downtime Upgrades without increasing the infrastructure cost. For more information about Enterprise Data Lake, see Data Lake scale.
In order for existing Data Lakes to be upgraded to Cloudera Runtime 7.2.18 or later version, they must be using Enterprise or Light Duty Data Lake. If you are using Medium Duty Data Lake and would like to upgrade to Cloudera Runtime 7.2.18 or later version, you will need to upgrade to 7.2.17 first and then resize your Data Lake to Enterprise Data Lake using the existing Data Lake resize functionality. Afterwards, you will be able to proceed with the upgrade to Cloudera Runtime 7.2.18 or later version.
