Can we use MapR Sandbox for preparing and practicing for the "MCCA - MapR Certified Cluster Administrator 5.1"???
You can do some of the lab exercises for ADM 2000 (Cluster Administration) using the Sandbox, but not all of them. For example, the Sandbox comes with MapR pre-installed, so you cannot do the installation lab. Also, several of the exercises in the lab guide rely on having a multi-node cluster, while the Sandbox is only a single node.
You can use services such as Amazon AWS or Google GCP to build a 3-node cluster that will let you do all of the exercises. But if you don't have that access, you will still learn a lot using the Sandbox. You will just need to modify (or skip) some of the labs.
Thanks for your reply. I have a i7 3.2 processor with 16GB RAM and 3TB HDD. I have installed Hypervisor in it to create VMs. Instead of going for AWS or Google, can i create my own cluster in the above system. If yes, where can i get the MapR software?
Our free on-demand course ADM 200 goes through installing a MapR cluster. The lab guide in the course materials will guide you through the process. Once you sign into learn.mapr.com, you can find the course at ADM 200 - Install a MapR Cluster.
I am talking the configuration of my system above mentioned.
Yes - with the setup you mention, you should be able to create three VMs, to create a three-node cluster. Once the three VMs are set up (and can communicate with each other), you can follow the instructions in the lab guide to install the MapR software on the nodes. Or, if you don't want to follow the lab guide, you can follow the instructions in the documentation (MapR 5.1 Documentation). Either one includes links to the software and instructions for installing.
Thanks Deborah. I have upgraded the system to 32 GB RAM. Will create 4 VMs and install 3 node cluster by following the lab guide or documentation. When I create 4 VMs, I will intstall Cent OS in it. If I do Map R Cluster installation process from that VM which has Cent OS, will the installation process create the Linux OS in the cluster or do i need to prepare the installation of OS prior to installing the 3 node cluster. I haven't gone through the material yet. However, I am curious to ask this question
MapR is installed on top of Linux, so you will want to have CentOS installed on all of your nodes prior to starting the MapR installation. The requirements for each node are detailed here: MapR 5.1 Documentation.
To create your nodes to be equivalent to the classroom set up, each node should have 6 disks. Have fun!
