1 ©2015 algorithmica.co.in Installation of CDH This document consists of six parts that illustrates entire Hadoop cluster setup: o Overview of Cluster setup o Creating First VM o Cloning First VM to get other Cluster machines o Installation of Cloudera Manager Server(CMS) o Installation of Cloudera Distribution of Hadoop(CDH) o Uninstalling CMS and CDH Part1: Overview of Cluster Setup High-level diagram of the VirtualBox VM cluster running Hadoop nodes The overall approach is simple. We create a virtual machine, we configure it with the required parameters and settings to act as a cluster node. This referenced virtual machine is then cloned as many times as there will be nodes in the Hadoop cluster. Only a limited set of changes are then needed to finalize the node to be operational (only the hostname and IP address need to be defined).

2 ©2015 algorithmica.co.in In this article, I created a 4 nodes cluster. The first node, which will run most of the cluster services, requires more memory (8GB) than the other 3 nodes (2GB). Overall we will allocate 14GB of memory, so ensure that the host machine has sufficient memory, otherwise this will impact your experience negatively. Part 2: Create the First VM with following configurations VM creation & startup Create the reference virtual machine as explained in document “4.a - virtualbox, vm” . Change the “Boot Order” to boot from HDD Do the following changes to allow VM access from outside world Settings ->Network o Set AttachedTo for BridgedAdapter o Set Advanced->Promiscuous Mode to Allow All Click on start to boot VM from Disk. Install GuestAdditions Guest Additions can be installed in a Virtual Machine, after installing the Operating System in it. It consists of device drivers and other applications which can optimize the performance and usability of a Virtual Machine. The Guest Additions can provide the following features: Mouse pointer integration Time synchronization Shared folders Seamless windows Shared clipboard Do the following steps to install guest additions: Update kernel and install software required to build kernl. o $> yum update kernel (to make sure we have up-to-date kernel) o $> yum install gcc o $> yum install kernel-dev Mount the GuestAdditions Image o Click on Devices-> Insert GuestAdditions CD Image (This will mount automatically)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
