Resize to Enterprise Data Lake if using Medium Duty Data Lake
If you are upgrading from Cloudera Runtime 7.2.17.200-7.2.17.500 to Cloudera Runtime 7.3.1, you must resize your Data Lake from Medium Duty to Enterprise Data Lake as Medium Duty Data Lake is not supported starting with Cloudera Runtime 7.2.18.
For information on why the Data Lake resize is needed, see Upgrading from Medium Duty to Enterprise Data Lake.
For information on how to perform the resize, see Data Lake resizing.
Prerequisites
Prior to resizing the Data Lake, ensure that the following are in place:
- Review the notes, limitations, and prerequisites listed in Data Lake resizing.
During this operation, the metadata maintained in your current Data Lake is automatically backed up, a new Enterprise Data Lake is created within the environment, and the metadata is automatically restored to this new cluster. As mentioned above, any custom cluster configuration that you previously made will need to be reapplied after the resize completes.
The maintenance window required for this operation depends on the size of your SDX metadata. When you open the Resize cluster UI, it will show you the estimated duration of the operation.
