Cloudera Operational Database (COD) supports custom EBS volumes for HDFS clusters while creating a database.

Rising Star

COD allows you to customize the attached storage worker node for an HDFS cluster while creating a database. You can define the EBS volumes for HDFS clusters.
You can also view the customized attached storage worker nodes using the ‘describe-database’ and ‘list-database’ commands.


This is available starting in COD v1.23 and you do not need to upgrade to a higher version of COD to benefit from this feature.
