On Hadoop, the MR3 distribution imposes no limit on the aggregate memory of worker Containers, so Hive on MR3 can run in a cluster of any size. On Kubernetes, the MR3 distribution can allocate up to 1 terabyte for the aggregate memory of worker Pods, so there is a limit on hardware resources that Hive on MR3 can utilize.
By purchasing a commercial use license, the customer can increase the limit on the aggregate memory of worker Pods on Kubernetes. For example, with a commercial use license for 10 terabytes, Hive on MR3 can exploit all the hardware resources in a cluster of 40 nodes each with 256 gigabytes of memory. We offer commercial use licenses from 1 terabyte in increments of 1 terabyte. For the duration of a commercial use license, the customer receives all updates to MR3 at no additional charge.
On behalf of our customers with a commercial use license, we provide technical support to assist in the deployment and maintenance of Hive on MR3. The customer can open a support request by sending an email to DataMonad. We deal with support requests 24 hours a day and 7 days a week. We always try to provide our customers with the best possible technical support.
