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 512 gigabytes 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.
A commercial use license costs $24,528 per terabyte per year (in US Dollars). This is equivalent to paying $0.175 per hour for a node with 64 gigabytes of memory. We also offer a discount program for commercial use licenses for large memory capacity.
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. We also assist in applying patches from Apache Hive back to Hive for MR3. In this way, we hope to foster collaborative relationships with our customers in the long term.
The customer can open a support request by sending an email to DataMonad. During business hours, the initial response time is usually within 2 hours after receiving the support request. Outside business hours, the initial response time is usually within 4 hours and no later than 8 hours after receiving the support request. 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.
For any question about commercial use licenses, our discount program, and technical support, please contact us.
